In a small bowl, whisk together Greek yogurt, lime juice, lime zest, hot sauce, and a pinch of salt. Adjust with water for desired consistency and chill.

Heat a large skillet over medium-high heat and add oil. Crumble in the ground beef and cook undisturbed for 3-4 minutes until browned. Stir and break into crumbles, cooking for another 3-4 minutes.

Reduce heat and stir in chile blend. Toast spices for 30 seconds, then mix in tomato paste, lime juice, and vinegar, scraping browned bits.

In a separate skillet, heat oil over medium-high heat. Sauté minced garlic until fragrant, then add cauliflower rice and cook for 3-5 minutes. Fold in lime juice and cilantro.

Assemble bowls with cauliflower rice, crispy ground beef, fresh veggies, drizzle yogurt-lime sauce, and garnish with cilantro.
