Heat up a saucepan and cook the ground beef, garlic, and all the spices for 3-4 minutes.
Add the black beans and tomato sauce and let simmer on medium/low heat for another 5 minutes or until the sauce becomes thicker.
Heat up some water in a small saucepan. When it comes to a boil, put the pre sliced zucchini in water for 30-60 seconds maximum. Then remove right away.
Lay some zucchini slices flat on a plate and pour some sauce on them. Keep repeating this operation for 2-3 times high. Then garnish with the chopped fresh tomato and scallions.
Serve hot and enjoy!
