Grill or fry burgers per package instructions
While burgers are cooking, heat refried beans in a small pot.
In a small bowl combine mayo and sriracha sauce and blend together.
Slice avocado into thin slices.
When burgers are done cooking, place each one on a piece of lettuce, and layer each burger with half of the refried beans (if using), sriracha mayo, salsa, avocado slices and tortilla strips (if using).
