Place one tortilla on a skillet over medium-high heat. Top with cheese and second tortilla. Once bottom tortilla starts to brown, flip the quesadilla and cook until cheese is melted.
Build your salad directly on top of your quesadilla. Layer lettuce first, then tomatoes, and then avocado. Sprinkle lime zest and then squeeze the lime juice over the top of the salad, making sure to get it mostly on the avocado. Sprinkle with salt and pepper. Toss the salad lightly together.
Add a dollop of sour cream and a few dashes of your favorite Mexican hot sauce over the top.
This quesadilla salad combo should be eaten with a knife and fork.
