Slightly adapted from Yotam Ottolenghi's Turkey & Zucchini Burgers
Preheat oven to 425 degrees F.
Combine all ingredients (except the searing oil) to make the burger mixture. Using clean, wet hands, mix well to combine. Be careful not to over-mix, resulting in dense burgers. Shape into ~8 burgers.
Heat a large cast iron or oven-safe pan. Add oil and heat over medium temperature.
Add the burgers to the pan, and sear until golden brown, about 2-3 minutes per side.
If you don't have an oven-safe pan, transfer to a baking sheet after searing.
Transfer the pan to the oven and cook for 5-7 minutes, or until just cooked through, being careful not to overcook.
Serve with cilantro vinaigrette or tahini sauce.
