Set your oven to 375F to preheat while you get the dish ready.
Wash and cut the vegetable into slices.
Set your stove to medium-high heat and place a frying pan on it. Pour in the ghee oil and sauté the onion for about 2 minutes. Add the ground beef and season with 1 teaspoon of taco seasoning. Allow it to cook for 3 minutes before removing from heat.
Now scoop a tablespoon of the spiced beef and add on top of the slices of zucchini. Put the zucchini in the preheated oven and allow to bake for 7 minutes.
Take out the zucchini from the oven and add the cheddar to it then bake again for an extra 3 minutes.
Remove from oven and add avocado and sour cream as the topping.
Serve in a plate and enjoy.
