Start by heating the black beans in a saucepan over medium heat. Stir occasionally to prevent sticking. The beans should be warm and soft. Their earthy aroma will fill your kitchen, making you hungry. Pro tip: Add a splash of water to keep them moist.

In a bowl, combine corn, diced tomatoes, and taco seasoning. Mix well until everything is evenly coated

Warm the taco shells in the oven for a few minutes. Crispy shells add texture to the dish. Keep an eye on them to avoid burning. If you prefer softer shells, wrap them in foil before heating.

Layer each shell with black beans, the corn mixture, avocado slices, and lettuce. The contrast of creamy avocado and crunchy lettuce is delightful. Take your time arranging the ingredients for a picture-perfect result.

Squeeze fresh lime juice over the tacos and sprinkle cilantro on top. The citrusy tang enhances all the flavors. Serve immediately while everything is fresh and warm. Enjoy the compliments from your guests!
