Preheat oven to 270F. Spread out tortilla chips on cookie sheet, sprinkle with 1/4c. finely grated cheese, and bake until cheese is melted and golden. Remove from oven and cool.
Put lime juice, honey, fresh cilantro,chipotle chili powder, garlic, sea salt, and black pepper into a small blender. Blend together until smooth, and pour into a glass bowl. Slowly fold in the mayonnaise, olive oil, and finely grated cheese.Blend all together, pour into a small glass jar, and set aside in a cool place until ready to use.
Wash and thoroughly dry the romaine.Tear into bite-sized pieces. Wash and dry the grape tomatoes. Cut into halves. Wash and dry the avocados. Score avocado skin along the north–south axis. Gently twist halves apart, and score the halves again north–south. Slice into quarters, pull from pit, peel skin away, and remove the pit. Cut each quarter in half and then into bite-sized chunks.
Just before serving, place romaine, tomatoes, cheese, avocados, and Creamy Chipotle Caesar Dressing into a large mixing bowl. Gently toss together. This can be plated immediately and served with a couple of the tortilla croutons on top, or you can serve this salad right from the bowl and put the tortilla chips in a pretty basket on the side.
