This is one of our favorites. I got the recipe from my friend Mary and we have enjoyed it time and time again.
2 chicken breast, no skin, no bone, cut in 1/2-inch cubes
4 teaspoons fresh lime juice, divided
2 tablespoons olive oil (more if necessary), divided
4 green onions, thinly sliced
2 large garlic cloves, thinly sliced
3/4 cup cooked black beans or 15 oz. can, darined
1 cup diced fresh tomatoes
1/2 cup red pepper
1 jalapeno pepper, seeded and minced (optional)
1 teaspoon kosher salt
1 tablespoon chopped fresh cilantro
1 pinch cayenne pepper
10 fresh corn tortilla shells, best cooked in hot oil
1/2 cup shredded mozzarella cheese, or Monterey Jack
1/2 cup sour cream
Stir 2 teaspoons lime juice and 2 teaspoons olive oil to coat chicken. Heat 1 tablespoon oil in a heavy skillet on medium-high heat. Stir-fry chicken for 1 minute until seared; remove with a slotted spoon, cover and keep warm.
Add 1 tablespoon oil to pan. Saute onions and garlic for 2 minutes until softened. Add beans, tomatoes, red pepper, and jalapeno. Saute 2 minutes to warm, shaking pan.
Gently stir in remaining 2 teaspoons lime juice, salt, cilantro and chicken. Cook for 1 to 2 minutes until warm. Taste, add cayenne and adjust seasonings. Serve in warm, crisp taco shells with cheese and sour cream. Buen Provecho!
