Place drained chickpeas and hearts of palm into the bowl of a food processor. Pulse until coarse and add 1/2 cup of the panko breadcrumbs.
Remove mixture to a large mixing bowl and add remaining ingredients.
Using an ice cream or cookie scoop, form uniform portions and place into more of the panko breadcrumbs. Roll around and then using your hands, form into patties.
Preheat a large saute pan over medium high heat. Add oil and the patties. Cook on the first side until golden brown, about 5-6 minutes. Flip and repeat.
Remove to paper towels to drain any excess oil.
Serve over mixed greens with lemon wedges and tartar sauce.
