Preheat your oven to 425°F. Chop the zucchini, red bell pepper, red onion, and halve the cherry tomatoes.
In a large oven-safe skillet, heat the olive oil over medium heat and sauté the minced garlic until fragrant.
Add the lean ground beef to the skillet. Cook, breaking it up with a spoon, until it begins to brown.
Stir in the chopped zucchini, red bell pepper, red onion, and cherry tomatoes. Sprinkle the dried oregano and basil over the mixture, season with salt and pepper to taste.
Create a small well in the center of the skillet and crack the egg into it. Allow the egg to cook until the whites are just set; you can stir it slightly if you prefer a mixed texture.
Transfer the skillet to the preheated oven and roast for about 8-10 minutes, or until the vegetables are tender and the egg is cooked to your liking.
Remove from the oven and serve warm, enjoying the vibrant flavors and balanced macros.
