Combine all ingredients in bowl. I use my hands to ensure everything is fully mixed. Form into four equal sized patties.
Preheat your grill to 300°F. Spray grill grates with olive oil to prevent sticking. Grill turkey patties for a duration of about 30 minutes, turning only once half way through the cooking process. Ground turkey should be cooked to an internal temperature of at least 16°F.
I like to top with a thick slice of sharp cheddar about 5 minutes before I'm done grilling.
Serve on a bun with your favorite toppings, including some green chile aioli.
