Skillet Beans and Rice

3/4 c long grain rice, cooked (I have substituted quick cooking rice
added directly to the recipe when in a real hurry)
1 each red & green bell pepper, cubed
1 med onion, chopped
1 small can (15 oz?) each black beans, kidney beans, pinto beans and
either cannelini or Great Northern beans (orig. recipe called for
Garbanzo, for which I don't care--basically you need four types of your
favorite bean)
1 small can tomatoes
1/2 c barbecue sauce (the strength of the suace can vary this amount)
Saute peppers and onions in water until tender. Drain and rinse beans and
add to skillet, along with tomatoes, barbecue sauce and 1 cup water. Cook
a minimum of 15 minutes, up to 2 hours to meld flavors. Add rice on top.
