Wash and dice sweet potatoes into bite-sized pieces. Place in a microwave-safe bowl, sprinkle with sea salt, cover, and microwave on high for 4-6 minutes.

Heat a large skillet over medium-high heat and add olive oil. Place steak in a single layer and sear for about 10 minutes, turning every 2 minutes until browned.

In the same skillet, add olive oil if needed, then add sweet potatoes, cooking for 3-4 minutes until golden-brown.

Create a well in the center of sweet potatoes and add minced garlic. Sauté for about 1 minute until fragrant.

Stir in diced bell peppers and sliced green onions, sautéing for an additional 3-4 minutes until tender.

Return seared steak and juices to the skillet. Pour in coconut aminos and cook for an additional 1-2 minutes.

Remove skillet from heat, toss in cracked black pepper and cilantro. Serve immediately.
