Heat olive oil in a large skillet over medium-high heat.
Add the ground beef to the skillet, breaking it up with a spatula, and cook until fully browned (approximately 5-7 minutes).
Drain any excess fat from the pan to ensure the vegetables do not become soggy.
Add the diced onion and chopped bell peppers to the skillet. Sauté for 4 minutes until the onion is translucent and peppers begin to soften.
Incorporate the sliced zucchini and minced garlic into the mixture. Sauté for an additional 4-5 minutes until the zucchini reaches a tender-crisp consistency.
Season the mixture with salt, black pepper, dried oregano, and smoked paprika. Toss thoroughly to ensure even distribution of spices.
Remove from heat and allow to cool slightly before portioning into four airtight meal prep containers.
