This is a very easy to prepare recipe for beans from a ranch in South Texas. It was originally posted at Best.pinto.beans.ever..... I don't know if they are the best ever, but they are very good and very easy to fix.
Note that this isn't the Ranch Style Beans like you can buy in the stores.
1 large onion, coarsely chopped
2 medium tomatoes, coarsely chopped
4 serrano peppers, finely chopped (w/seeds)
1 cup cilantro, finely chopped
2 cups "Clamato" juice
2 cans of Bush's pinto beans
6 strips of bacon
1 Tbs oil (or lard)
Cook the chopped onion in hot oil (lard) until it begins to soften.
Add the bacon.
When the bacon starts to brown, add the beans and stir in the remaining ingredients.
Simmer for 45 minutes.
The amount of heat you end up with is highly dependent on the size and heat of the serrano peppers. Four large serrano peppers may be almost unbearably hot while four small serrano peppers may be too boringly mild. So adjust the number of your serrano peppers to your taste.
