Prepare the red pepper sauce by combining all of the ingredients together in a blender or food processor, then refrigerate while preparing the chicken.
Cut the bacon slices in half, and cook until browned and crisp, then move to a paper towel lined plate to drain off any grease.
Using a grill or grill pan, cook the chicken 3-5 minutes per side, depending on your cooking method and thickness of the chicken breasts.
Meanwhile, slice the tomatoes and avocado (or prepare guacamole), and toast bread.
To prepare the sandwiches, spread 1 tablespoon of the creamy red pepper sauce onto the bottom side of each roll, top a leaf of lettuce, chicken, tomato slices, avocado slices or guacamole, and 3 of the bacon slices. Spread a tablespoon of the sauce on the remaining rolls and place on top.
