Spinach Chicken Burgers

1 Preheat the oven to 400 F
4 Line a sheet-pan with parchment paper and drizzle some olive oil. 
2 Add the ground chicken to a bowl with the spinach, breadcrumbs, egg, mustard, diced shallot and spices. Mix well with your hands until evenly incorporated.
3 With oiled hands, shape the mix into 6 equal burgers. Place the burgers onto the pan, then drizzle each one with more olive oil.
5 Bake the burgers for about 18 minutes, flipping halfway through. Set them under the broiler for 2 minutes at the end to brown.
6 Serve with a salad or in a bun with your favorite toppings.
