In a small saucepan, heat refried beans over medium heat. Stir in cumin and hot sauce/salsa. Reduce heat to low.
In a medium saute pan, heat olive oil over medium heat. Add onions and peppers. Saute until completely soft (about 10 minutes). To speed up the process, periodically add a tablespoon of water and cover. The water will steam up right away allowing the peppers and onions to soften.
When the onions and peppers are soft, add chopped rib meat. Saute for about 4-5 minutes. Remove from heat.
Heat a large flour tortilla in the microwave for about 10 seconds to soften. Remove from microwave and smear about 2-3 tablespoons of beans on half of the tortilla. Layer on about ⅓-1/2 cup of rib meat and peppers. Add a layer of shredded cheese.
Fold the other half of the tortilla over. Smear a thing layer of butter on half.
Heat a large saute pan over medium heat. When the pan is hot, add the folded quesadilla buttered side down. While the quesadilla is cooking, butter the other side.
After about 3 minutes, flip and cook for about another 3 minutes. Tortilla should reach a nice golden brown. Repeat the process for the other tortilla unless your pan is large enough to fit two. Mine isn't!
Serve with your favorite dippers (sour cream, guacamole, salsa, queso) and enjoy!
