These cheese-filled treats are made with tortillas, the traditional unleavened bread wrappers of Mexico. And whole-wheat tortillas are a great way to add grains to your day.

Preheat the oven to 350 F.

Drain and rinse black beans.

In a bowl, combine the black beans, 1/2 cup onion and cumin.

Sprinkle each tortilla with 1/4 cup of cheese.

Divide the bean-onion mixture among the tortillas — spread it over cheese.

Fold each tortilla in half.

On a lightly greased 9-by-13-inch baking pan, place the tortillas with space in between and cover with foil.

Bake for 5 minutes until cheese is melted. Then fold each tortilla in half. Cover with the foil and bake 5 to 10 minutes longer.

While quesadilla is baking, in a bowl combine remaining onion, tomatoes, jalapeño, garlic, cilantro leaves, and lime juice. Mix well.

Remove the foil from pan.

Cut each tortilla into 4 pieces. Serve with a tablespoon of plain low fat Greek yogurt and tomato mixture.
