Southwestern Dense Bean Salad Recipe | High Fiber High Protein Meal

I’ve written before about how nobody warns you about the GI side of GLP-1 medications — the constipation, the bloating, the “why won’t things just move” days.

Fiber became non-negotiable for me once I understood that, and it’s part of why I keep coming back to dense bean salads.

The Mediterranean version I shared is one of my regulars, but some weeks I want something with more kick — smoky, a little spicy, and closer to taco night than a Greek plate. This Southwestern version scratches that itch. Black beans, corn, bell pepper, red onion, and a lime-cumin dressing that ties it all together.

Same idea as before: it’s a “dense” bean salad, meaning the beans are the point, not an afterthought scattered on top of lettuce. That’s exactly why it works so well for hitting protein goals on GLP-1 — it’s a real meal, not a side dish.

On a GLP-1? Why You Should Add this Recipe to Your Meal Plan

This one checks the same boxes as my Mediterranean dense bean salad version, with a different flavor profile:

• High in fiber from black beans and corn (11 to 13g)— genuinely helpful for GLP-1-related constipation
• Solid plant-based protein base, and easy to boost further (see below)
• Zero cooking required — just chop, rinse, and stir
• Tastes better on day 2 and 3, so it’s an easy make-ahead lunch
• Naturally portion-flexible if your appetite is low that day
• Under 300 calories – and so filling!

Easy Meal Prep

Just like the Mediterranean salad, I make this in one big batch on Sunday and let it sit in the fridge all week. The lime juice and cumin actually mellow out and deepen after a day or two — it tastes more “finished” on Tuesday than it does the moment you make it.

If You’re Dealing with GI Issues on GLP-1…

If you’re newer to GLP-1 medications and dealing with constipation or bloating you weren’t expecting, you’re in good company — it’s one of the most common side effects of Wegovy, Zepbound, and Mounjaro, even though it rarely gets talked about openly.

Working more fiber into meals you’re actually going to eat again and again (instead of choking down a fiber supplement) has made the biggest difference for me. This salad is one of two or three “regulars” I keep in rotation for exactly that reason.

If you want more ways to build fiber and protein into meals without it feeling like a chore, I go into more of that in my guide to plant-based eating on GLP-1 medications.

Estimated Nutrition (Per Serving, makes 6 servings):

Calories: ~280 | Protein: 12–14g | Fiber: 11–13g | Carbs: 34g | Fat: 9g

(Varies depending on exact bean brands and corn used.)

Ingredients

• 1 can black beans, drained and rinsed
• 1 can kidney beans, drained and rinsed
• 1 cup corn (fresh, frozen and thawed, or canned and drained)
• 1 orange or red bell pepper, diced small
• 1 cucumber, diced small
• 1/4 red onion, finely chopped
• 2 tbsp fresh cilantro, chopped

Dressing:

• Juice of 1–2 limes
• 2 tsp extra virgin olive oil
• 1 tsp garlic powder
• 1 tsp onion powder
• 1 tsp smoked paprika
• 1 tsp chili powder
• 1 tsp ground cumin
• 1/2 tsp salt
• 1/4 tsp black pepper

Optional Add-Ins

• Diced avocado, added right before serving
• Shredded rotisserie chicken or grilled shrimp for extra protein
• A drained can of black beans swapped for pinto beans for a milder flavor
• A finely diced jalapeño for more heat

Instructions

Step 1: Prep the Beans and Vegetables

Drain and rinse the black beans and kidney beans well, then pat dry. Dice the bell pepper, cucumber, and red onion. Chop the cilantro.

Step 2: Make the Dressing

In a small bowl or jar, whisk together the lime juice, olive oil, garlic powder, onion powder, smoked paprika, chili powder, cumin, salt, and pepper.

Step 3: Combine Everything

In a large bowl, combine the beans, corn, chopped vegetables, and cilantro. Pour the dressing over top and mix well.

Step 4: Let It Marinate

Refrigerate for at least 30 minutes, though it tastes even better after a few hours or overnight. Store in an airtight container for up to 4–5 days.

Optional Protein Boost

Want to push this well past 20g of protein per serving? Stir in shredded rotisserie chicken, grilled shrimp, or leftover taco meat. If you’d rather keep it plant-based, check out these 15 ways to add extra protein to vegetarian meals — several of them work well folded right into this salad.

A Few Easy Tweaks

• Swap kidney beans for pinto beans if you want a milder flavor
• Add crumbled cotija or feta if you don’t need this dairy-free
• No fresh corn? Frozen and thawed works just as well as canned
• Make it a full meal by serving over a scoop of cauliflower rice or alongside grilled chicken

Hope this one becomes as regular a lunch for you as it has for me.
