Put half of the beans and half of the jalapenos in a blender/food processor and lightly chop it. Dump this into a mixing bowl (I just dump it right into the bowl that I will be serving it in), and add the rest of the beans.
Add as much tomato sauce as you want, depending on how thick you want it. At this point, you may want to taste it because that escabeche sauce is HOT. I never add the rest of the can, but some people like it spicy.
Sauté garlic and chilies and mix it in (or just add the powders).
Serve with tortilla chips or as a topping over burritos.
