Habichuelas is an inherent part of our culture and one of the components of La Bandera Dominicana (The Dominican Flag), our traditional lunch. It is traditionally prepared...

If we are using canned beans how much water do we add to the part that states add the remaining water.

Fill up the can with water and add that.

I thought that this recipe included green peppers or some kind of pepper.
Please correct me if I am wrong. I remember my mom adding peppers to this recipe.

We don't in my family, but if your family does, go ahead.

I will have to try this out. Sounds delicious. In my family they've always used roman beans. My grandmother gets so upset when we cannot find them for her. Nothing like dominican beans over concon!

If I use the dried beans, after soaking them overnight should I boil them before making the recipe? If so for how long?

You should change the water in which you soaked it, and then boil it soft. How long depends on a lot of things (your type of stove, pot, temperature, etc.). If you have a pressure cooker you can do this in half an hour, a regular pot may take up to two hours simmering at medium heat.
