Try These Twists!
Muffuletta Burgers: Stir 1/2 cup chopped pimiento-stuffed Spanish olives into meat mixture. Proceed as directed. Pulse 1/2 (16-oz.) jar mixed pickled vegetables, drained, and 2 Tbsp. Italian dressing in a food processor until coarsely chopped. Top each burger with vegetable mixture and salami, ham, and provolone cheese slices.
Note: We tested with Mezzetta Italian Mix Giardiniera pickled vegetables.
Green Tomato-Feta Burgers: Stir 1 (4-oz.) container crumbled feta cheese, 1 Tbsp. finely minced red onion, and 1 tsp. minced oregano into meat mixture. Proceed as directed. Top each burger with sliced pickled green tomatoes, lettuce, thinly sliced cucumber, a pinch of dried crushed red pepper, and a fresh dill sprig.
Pickled Onion-Chutney Burgers: Stir 2 Tbsp. finely chopped red onion and 1/3 cup mango chutney into meat mixture. Proceed as directed. Top each burger with a small wedge of blue cheese, arugula, whole grain Dijon mustard, and Red Onion Relish.
Great flavor! I would really recommend using a grill pan.
