Lightly spread 4 tortillas with a bit of guacamole or sour cream. Spoon filling down the center of tortillas. Add toppings saving a good bit of the cheese for sprinkling over them after they are rolled.
Roll up & place on a microwave safe dish. Sprinkle with remaining cheese & microwave only until cheese is melted. Top with sliced green onions & tiny grape tomatoes. Serve extra toppings on the side if you like.
