Take out about 500g of cooked beans from the pot along with the broth. Place it in a smaller pot, heat it up and let the liquid evaporate so that you get a thick sauce. Remove from the heat.
Wash and slice tomatoes, jalapenos, and cilantro. Peel and slice the avocado.
Open a can of sweet corn and rinse it well.
Place a pan over medium heat.
Heat up the tortillas about 30 seconds each side.
Put the tacos together. Take a tortilla and put 2 tablespoons of bean in it. Top the beans with chopped tomatoes, jalapenos, cilantro, sliced avocado, and a handful of sweet corn.
Squeeze some lime juice on the taco before serving.
