Refried Black Beans

This is one of my recipes that I pretty much created by completely changing a recipe. It's one of my favorites because I love refried beans.

1 t canola oil
1/2 c. chopped onion
2 large garlic cloves, mince
3/4 t cumin
1 15oz can of black beans, undrained ( I have used kidney beans or red beans before too)

Saute onion and garlic for 2 min. in oil in a small saucepan. Add cumin and stir. Then add the black beans and mash with potato masher partially. Simmer 10 min or until thickened.
