Bacon-Wrapped Keto Meatloaf

Preheat oven to 400°. Grease a medium baking dish with cooking spray. In a medium skillet over medium heat, heat oil. Add onion and celery and cook until soft, 5 minutes. Stir in garlic, oregano, and chili powder and cook until fragrant, 1 minute. Let mixture cool slightly.  In a large bowl, combine ground beef, vegetable mixture, cheese, almond flour, Parmesan, eggs, soy sauce, and season with salt and pepper. Shape into a large loaf in baking dish, then lay bacon slices on top.  Cook until bacon is crispy and beef is cooked through, about 1 hour. If bacon is cooking too quickly, cover dish with foil.
