Set up your 'bowls' by adding shredded lettuce and a few drizzles of vinaigrette dressing.
Heat the olive oil in a skillet and add the bell pepper slices and onion slices to the skillet and saute over high heat for 4 to 6 minutes, stirring often. Once the onions have turned opaque and bell peppers have browned and softened, remove from the heat.
To the same skillet, add the sliced chicken and add the taco seasoning and saute the chicken for 5 to 7 minutes, or until cooked through. Once the chicken has cooked, add the peppers and onions back in with the chicken and keep warm over low heat until ready to serve.
In a small bowl, mash the avocados with the lemon or lime juice, cilantro and salt. (Add the red onion and jalapenos, if desired.)
Add the chicken and bell peppers and onions over the shredded lettuce and top with spoonful of homemade guacamole.
