To serve: Buns, avocado, tomato, lettuce, onion slices, pickles, ketchup, mustard and any other toppers that sounds delicious!
Add all ingredients to a large bowl. Mix until just combined.
Form into 4 patties, about ½ inch thick. Use your thumbs to make a depression in the center of each patty. Place on a cookie sheet coated with nonstick spray and hold in the fridge until ready to grill or cook on the stovetop.
Grill: Grill for a few minutes on each side until cooked to desired level.
Stovetop: Heat olive oil in a nonstick skillet or griddle over medium-high heat. Once oil is shimmering, cook for 4-5 minutes per side until reaching desired level.
