Whoever said salads can’t be filling for lunch alone can be proven wrong with this protein-rich bean salad. More than just the filling, this recipe is super delicious, easy to make, and full of flavor. Beans are a good source of protein and high in soluble fiber, which is helpful in keeping blood cholesterol levels low. First, you cook the pre-soaked beans in a pressure cooker. Combine them with diced tomatoes, onions, and bell peppers. For the sauce, mix olive oil with white wine vinegar, mayonnaise, mustard, black pepper powder, and salt. Add ice and your healthy lunch is ready.
