Heat the olive oil in a large skillet. Add the onions, red bell peppers, garlic and jalapeno and saute until tender, 3 to 4 minutes. Add the chicken and saute until browned, breaking it up with the back of a wooden spoon as you cook. Stir in the chili powder and cumin and let toast for a few stirs. Add the beans and let cook until warmed through.
Mix the yogurt and salsa together in a small bowl.
Toss the chopped lettuce, cherry tomatoes, tortilla chips, cheese, cilantro, sauteed chicken and bean mixture all in a large bowl and dress with the yogurt and salsa.
