Ingredients

• 1 pound Beef sirloin, thinly sliced
• 1 medium Red bell pepper, sliced
• 1 medium Green bell pepper, sliced
• 1 medium Yellow bell pepper, sliced
• 1 medium Onion, sliced
• 0.25 cup Coconut aminos
• 3 cloves Garlic, minced
• 1 tablespoon Ginger, minced
• 2 tablespoons Avocado oil
• 0.5 teaspoon Salt
• 0.25 teaspoon Black pepper
• 1 tablespoon Sesame seeds (optional)
• 2 stalks Green onions, sliced (for garnish)

Directions

Step 1

Begin by preparing all the vegetables: slice the red, green, and yellow bell peppers into thin strips and slice the onion into thin wedges.

Step 2

Thinly slice the beef sirloin against the grain to ensure tender pieces once cooked.

Step 3

In a large skillet or a wok, heat 1 tablespoon of avocado oil over medium-high heat.

Step 4

Add the thinly sliced beef to the hot skillet and season with salt and black pepper. Stir fry the beef, stirring occasionally, until browned and cooked through, about 5-6 minutes. Remove the beef from the skillet and set it aside.

Step 5

In the same skillet, add the remaining tablespoon of avocado oil. Add the minced garlic and ginger, sautéing for about 30 seconds until fragrant.

Step 6

Add the sliced onions and bell peppers to the skillet, and stir fry for about 4-5 minutes until the vegetables are slightly tender but still crisp.

Step 7

Return the cooked beef to the skillet, adding the coconut aminos. Stir everything to combine and cook for an additional 2-3 minutes, allowing the flavors to meld together.

Step 8

Taste and adjust seasoning if necessary.

Step 9

Serve the beef stir fry hot, garnished with sesame seeds and sliced green onions, if desired.
