Trim off and discard the ends of the zucchini; halve the zucchini lengthwise, then cut the halves crosswise into ¼-inch-thick half-rounds at an angle. Transfer to a large bowl.
Trim off and discard the ends of the onion and remove the outer layer; small dice the onion into ¼-inch pieces. Add to the bowl with the zucchini.
1 medium yellow onion
Trim off and discard the root ends of the garlic; peel and mince or press the garlic. Add to the bowl with the zucchini and onion.
4 cloves garlic
Add coconut oil to a nonstick skillet and preheat over medium-high heat.
1 tbsp virgin coconut oil
Add the ground beef to the skillet; cook, breaking apart with a spoon, until browned and crumbly, 3 to 4 minutes. Once done, transfer to a bowl, leaving some of the juices in the skillet.
1 ½ lb lean ground beef
Once the beef has been transferred, add the zucchini, onion, and garlic to the skillet. Cook, stirring frequently, until the vegetables are tender and lightly browned, 4 to 6 minutes.
Using a knife, shave the cilantro leaves off the stems at a downward angle, working away from your body; discard the stems and finely chop the leaves. Transfer to a small bowl.
Add chili powder, cumin, salt, and pepper to the skillet; stir to combine.
2 tsp chili powder
1 tsp cumin
1 tsp salt
½ tsp black pepper
Return the ground beef to the skillet and add in about ¾ of the cilantro (save the rest for garnishing); stir to combine.
Divide the meal between plates and garnish with the remaining cilantro. Enjoy!
