In a tiny bowl, combine minced garlic and oil. Season well with salt and pepper and allow it to sit for 10 minutes or so, mixing it occasionally.
Combine the veal, seasoned garlic oil mixture, egg yolk, red onion, parsley, feta and lemon juice in a mixing bowl. Season with additional salt & pepper. Form into four (4) quarter-pound patties.
For the Mediterranean Salsa Topping, combine all ingredients in a small bowl, season with salt and pepper and toss. Set aside.
Cook patties in a lightly oiled grill pan or on your outdoor grill for approximately 5-6 minutes per side or until internal temperature is 160 degrees.
Top burgers with your Mediterranean Salsa. If using a bun, place greens, then burger then salsa onto the bun. If using mayonnaise or another condiment, place that below the greens. Enjoy!
Notes: Always brush and oil your grill before using for best success. If you enjoy cheese on your burger, feel free to add your favorite cheese to the burger just before its done cooking. The feta in and on the burger does give some great flavor, so additional cheese is not necessary.
You can use garlic paste in place of the minced garlic, however making your own garlic oil adds depth of flavor and moisture to these burgers. It's a great tip!
