Ingredients

• 12 oz lean ground beef
• 1 cup, thinly sliced bell peppers
• 1/2 cup, thinly sliced red onion
• 2 cloves, minced garlic
• 2 tbsp avocado oil
• 3 tbsp coconut aminos
• 1 tbsp apple cider vinegar
• 1/4 tsp chili flakes
• 1/2 tsp salt
• 1/4 tsp black pepper

Instructions

1. Step 1: Heat 1 tbsp avocado oil in a large non-stick skillet over medium-high heat until shimmering. Add 12 oz ground beef, breaking it into small crumbles with a spatula until golden-brown and fully cooked (5-6 minutes), then drain excess fat.
2. Step 2: Add remaining 1 tbsp avocado oil, 1 cup sliced bell peppers, and 1/2 cup sliced red onion to the skillet. Sauté for 3-4 minutes until vegetables are crisp-tender and edges are slightly charred.
3. Step 3: Stir in 2 minced garlic cloves and cook for 30 seconds until fragrant, then add 3 tbsp coconut aminos, 1 tbsp apple cider vinegar, 1/4 tsp chili flakes, 1/2 tsp salt, and 1/4 tsp black pepper. Simmer for 2 minutes until sauce thickens and coats the back of a spoon.
