Cut the chicken breast halves lengthwise into ½-inch wide strips.
In a medium bowl, combine the tomato paste, chili powder, garlic powder and 1 tablespoon olive oil. Add the chicken strips and stir to coat. Marinate for 10 minutes.
MAKE THE SALSA:
In a medium bowl, combine the mango, avocado, red pepper, cilantro and the juice of 1 lime. Season with salt and pepper to taste. Cut the remaining lime into wedges.
COOK THE CHICKEN AND SERVE:
Heat the remaining 2 tablespoons of olive oil in medium sauté pan over medium-high heat. Season the chicken strips with salt and pepper. Sauté the chicken strips, stirring often, until they're firm to the touch and uniformly opaque, 3 to 4 minutes. Turn off the heat and let sit for 1 minute.
Set the chicken strips on a platter, top with the salsa, and serve with lime wedges.
Notes
If you're preparing this dish as GLUTEN FREE, just be sure to use a brand of garlic powder that is know to be GF.
Look for just ripe avocados and mangoes. They should give slightly when flesh is squeezed (not too soft).
Try serving this inside corn tortillas for a little taco action!
