Grate potato, carrot and zucchini in a food processor or by hand. Plave together in a large mixing bowl.
Add the seasoning and chia egg to the bowl. Mix together well, preferably with your hands. Taste test and add more seasonings if desired.
Scoop up about 1/3 cup of the mixture. Squeeze mixture together firmly over a sink or bowl to remove excess water.
Shape vegetable mixture into round flattish circles about 2-1/5 to 3 inches in diameter. Press each together well so they don't fall apart. Set each aside, making sure they aren't touching, on a lined baking sheet.
Coat a large non stick skillet well with oil using a pastry brush. Heat over medium low heat.
When pan is hot, fry latkes for 2–3 minutes, gently pressing down with spatula while frying, Flip and fry the other side for another 2 minutes. Add more oil if they begin to stick.
Continue frying until all the latkes are cooked.
Serve immediately with chopped gren onion, sour cream and applesauce.
Notes
These are a low fat version of traditional fried latkes. If you don't have a non stick skillet or like a deep fried taste, you will need to use 1/2 cup oil for frying.
