Heat oil in a pan, add the jalapeno and cumin. Stir until the jalapeno softens slightly. Add the beans, and stir. Add the broth.

Simmer about five minutes, until beans are heated through and they've absorbed some of the broth and seasoning. Mash the beans. Stir them in the pan until they absorb most of the liquid. Set aside.

Take 3 tortillas for each person. Microwave for 30 seconds to warm them and make them pliable. Cut cheese into six sticks per person.

Use 1/4 of the bean mixture for 3 tacos. Put a spoonful in a tortilla, add 2 pieces of cheese and wrap the tortilla around the filling. Repeat with the other two tortillas.

If the bean mixture is still hot, serve. If it has cooled, microwave 1 minutes to reheat.
