Set oven to 375F.
Wash portobello mushrooms and remove stem. Dry them with a paper towel.
Place them face down in a baking pan and lightly spray with olive oil. Sprinkle a little sea salt and garlic.
Bake in the oven for 8 – 10 minutes.
Season with your ground chicken with your choice of seasonings. I recommend sea salt, garlic, cumin, cayenne, paprika.
Form a hamburger patty and cook in a skillet on medium heat. Remember to flip the patty so that the inside and sides of the patty are completely cooked.
Remove the mushroom caps from the oven and immediately begin to assemble your burger.
Place the mushroom cap face up. Add: lettuce, cabbage, tomato, chicken burger patty, goat cheese (crumble or spread), avocado, carrots.
Top the burger with the other end of the mushroom cap. Smash it down with your hands and eat!
