In a large bowl, mix all the ingredients together. Form the
mixture into 12 patties.
Spray a large, nonstick skillet with cooking spray and place over
medium heat. Add the patties and cover. Cook until browned
and juices run clear, about 5 minutes on each side. If using a
thermometer, cook until internal temperature reaches 165 F.
Transfer to a serving platter and serve immediately.
For a milder flavor, use 1 teaspoon rosemary instead of the sage,
black pepper and red pepper flakes. For an Italian flavor, try 1
teaspoon of basil and 1/2 teaspoon of fennel instead of the sage
and red pepper flakes.
