Portobello Burger with Muffuletta Topping

Total Time

Prep/Total Time: 25 min.


1 serving

A tasty tomato-olive mixture, melty cheese and smoky grilled mushroom add so much flavor to this recipe that one taster called it “one of the best mushroom burgers I’ve had.” For a change, switch another cheese or spinach for the provolone and lettuce. —Tamra Duncan, Lincoln, Arkansas
