Place ground turkey, breadcrumbs, herbs, mayonnaise, curry powder, lemon zest, salt and pepper into a large bowl. Mix (I find your hands are your best tools here) until just combined. Overmixing meat leads to a weird chewy dense texture that most people find unpleasant.
Split mixture into even amounts and form into patties. I usually get 4-6 patties, depending on the size I'm making that day, which is usually dictated by what sides we're having.
Heat a large skillet over medium heat and add oil. Once the skillet is hot, add the patties and cook until they've formed a nice crust on the bottom, or about 3-4 minutes. Flip and cook on the other side for another 3-4 minutes. Remove from pan and let rest.
Not necessary, but definitely nice- butter the inside of the buns and put them in the still-hot pan until they're toasty and buttery like the outside of a grilled cheese. About one minute. If you're not already toasting your buns, doooooo it.
Spread tzatziki on buns, add lettuce, and serve.
