Prep all ingredients by measuring, washing or simply laying out next to grill or stovetop for convenience while cooking.
In a cast-iron skillet over medium heat or on the grill, cook turkey burgers for 5 to 7 minutes on one side.
Then flip and top each patty with marinara and a slice of cheese.
Cook another 5 to 7 minutes, until fully cooked and cheese is melted.
Toss lettuce with pesto, then top with the patties, and drizzle with more pesto to serve.
