Mix your mashed chickpeas with the spices (salt, pepper, oregano, garlic, parsley), chopped ginger, onion, carrots, tomato paste, and beet pureé. You should have a paste-like consistency full of colors.
1*) Feel free to add cornstarch or oats if you want a more solid burger.
Place on an oiled pan at medium heat for 3 minutes per side or until you have a nice golden brown on each side.
Assemble your burger using the buns, guacamole, and spinach.
