Put the chicken in a bowl and add the zucchini, carrot, scallion, hummus, parsley, garlic, coriander and cumin.
Mix the meat and flavorings together by hand, or with a wooden spoon, until evenly combined.
Form into four burgers, about 1/2-inch thick.
(If the mixture is very soft, transfer the burgers to a plate and refrigerate for 10 minutes.)
2.
Heat a nonstick skillet over medium heat.
Brush burgers lightly with olive oil and season with 1 1/2 teaspoons salt and some pepper.
Add burgers to the pan and cook until browned and cooked through, about 5 to 8 minutes on each side, or until an instant-read thermometer inserted into the sides of the burgers registers between 165 and 170 degrees F. Set aside to rest for 5 minutes.
Serve burgers on a toasted bun or in a pita with toppings as desired.
