Dependiendo de la variante del español que utilices, opta entre frijoles, judías o habas. "BBQ", si no hace referencia a una salsa, sino a la forma de preparación, yo lo traduciría por "a la parrilla". Si es una salsa, entonces "con salsa barbacoa".

O preparados/as al estilo barbacoa. Si es para España, creo que es mejor que utilices "judías". Te adjunto una receta de "BBQ beans" para que veas que tan sólo es una forma de prepararlos.

Hard Rock Cafe BBQ Beans

2 15-ounce cans pinto beans (with liquid)
2 tablespoons water
2 teaspoons cornstarch
1/2 cup ketchup
1/3 cup white vinegar
1/4 cup brown sugar
2 tablespoons diced onion
1 teaspoon prepared mustard
1/2 teaspoon chili powder
1/4 teaspoon salt
1/4 teaspoon coarse ground black pepper
1/2 cup cooked bacon

Preheat oven to 350 degrees.

Pour entire contents of the can of pinto beans into a casserole dish (with a lid).

Dissolve the cornstarch in a small bowl with the 2 tablespoons of water. Add this solution to the beans and stir.

Add the remaining ingredients to the dish, stir well and cover.

Bake for 90 minutes or until the sauce thickens. Stir every 30 minutes. After removing the beans from the oven, let the beans cool for 5 to 10 minutes before serving.

Serves 6 to 8 as a side dish.

suerte!
