Place the chicken breast in a bowl with the lime juice, cumin, smoked paprika and olive oil and allow to marinate for 2 to 4 hours.
Preheat the oven to 350 degrees Fahrenheit.
Put the chicken and marinade in a baking dish and bake in the oven for 20 minutes or until the chicken is cooked through. Once cooked, remove from the oven and allow to cool before cutting into bite-sized pieces.
To make the salsa, chop up the tomatoes, onion, jalapenos and cilantro and place in a bowl. Sprinkle with salt and stir in the lime juice.
Place a won ton wrapper into each cup of a muffin tin and spray lightly with olive oil. Bake in the oven for 5-6 minutes or until crisp and golden in color.
Fill each won ton cup with shredded lettuce, a spoonful of black beans, chicken, mashed avocado and salsa. Serve.
