Grate the zucchini and drain the juice as shown in the video
Grate half of the lemon zest using a small grater
Add all other ingredients and mix well until the mixture is homogeneous
Form patties about 1.5 in diameter
Place on a baking sheet covered with baking paper
Cut tomatoes and place one slice on each patty. Salt and pepper the tomatoes.
Bake 20-25 minutes in a preheated to 425*F oven
Notes
In this video, I baked patties for 10 minutes without tomatoes, then for 15 more minutes with tomatoes. But I realized that placing tomatoes on the patties from the beginning works better.
