1-First Steps: Prep and Sauté First, drain and rinse all three types of beans thoroughly to remove excess sodium and prepare them for cooking. Heat the olive oil in a large pan over medium-high heat, then sauté the diced red onion and bell peppers for about 5 minutes until they are tender. This builds a flavorful base that infuses the beans with sweetness and crunch.

2-Combining and Seasoning: Stir in the rinsed and drained black beans, pinto beans, and red kidney beans, along with the chopped cilantro, lime juice, and taco seasoning. Cook the mixture until it’s heated through, then season with salt and black pepper to taste. These steps ensure the beans absorb the seasonings fully, creating a rich filling that’s full of taste and nutrition.

3-Assembly and Serving: Warm the taco shells or tortillas in a dry pan for 30 seconds on each side to make them pliable. Assemble the tacos by spooning the bean mixture onto each one, then add desired toppings such as fresh cilantro, diced tomatoes, and avocado slices. Serve immediately while warm for the best experience, and feel free to adapt for dietary preferences as you go.
