Turkey, while being a lighter alternative than the preferred 80/20 ground beef combination, does, unfortunately, lack flavor. Turkey, like tofu, needs to have essence and zest infused in order for it to be tasty.
Brush raw turkey patties on both sides with garlic-flavored olive oil and Worcestshire sauce. Season with kosher salt and freshly-ground pepper. Add your favorite steak rub and a sprinkling of Chipotle Chile Pepper.
Prepare a basting sauce of Worcestshire, melted garlic butter and chopped chives. When patties are browned on one side, flip and baste, then repeat for the other side.
Nothing beats a real ground beef grilled burger, but raising the flavor quotient on your turkey burger will at least get it into the race.
