Heat a large skillet or pot over medium heat.
Add oil. This recipe uses less oil to sauté the seasoning. Therefore, to prevent the seasoning from burning during the sautéing process, keep ½ cup of water on hand and add 1 tbsp of water, at a time, to areas where you see the seasoning may stick.
Add onions, ½ tsp of salt, and stir gently for two minutes, until onions are translucent.
Add peppers and gently stir for 2 minutes.
Add garlic and stir for 1 minute
Add ¼ cup of water, stir, cover pot and let simmer for 10 minutes. You may need to add a bit of water after 5 minutes to prevent sticking.
Add cooked beans and a ½ cup (or more) of liquid from the cooked beans, or water. Cover and let simmer for 10 minutes.
Taste and, if needed, add salt.
Remove from heat and mash beans using a wooden spatula, or potato masher, to desired texture.
