Hot Black Bean and Salsa Dip

I made this dip for Spencer's Bday party yesterday.  Everytime I make it; it is gone!

You will need:
1 can of black beans, rinsed and drained
1 cup of jarred salsa
1 tbsp-1 1/2 tbsp chili powder
Chopped large tomato

Mix everything and simmer for 20 minutes.  Serve with tortilla chips.
