First prepare the sweet potatoes. You’ll pre-cook them in the microwave so that they pan-sear quickly later in the recipe. Dice a large sweet potato into 1″ chunks, place into a microwave-safe bowl, sprinkle with sea salt, then cover and microwave until tender, but not soft – anywhere from 4-6 minutes. They’re ready when you can insert the tip of a knife into a piece and meet just a bit of resistance. Be mindful not to overcook or you’ll end up with mush. No bueno.

Pat your steak dry with paper towels or a clean kitchen towel, then trim of any excessive fat and sinew; dice into 1″ pieces. Heat a cast iron skillet over high heat and add 2 tablespoons olive oil. Add the diced steak to the pan in a single layer and allow the pieces to sear for about 2 minutes. Turn the pieces and sear for another 2 minutes per side, about 10 minutes total.

At around the 10-minute mark, the steak should be seared and slightly charred on the outside and medium on the inside. AKA, perfect. Remove the steak from the skillet using a slotted spoon and set aside onto a plate.

Reduce the heat to medium low, add another tablespoon of oil to the pan, and then add the sweet potatoes. Toss ’em in the fat and saute until slightly charred, about 4 minutes. Give them a good stir halfway through. If they start to stick, add a bit more oil.

  • Make a well in the center of the pan and add the garlic. Sautee, stirring occasionally, until fragrant, about 1 minute.
  • Add the bell pepper and scallions and toss with the potatoes. Sautee, stirring occasionally, until the peppers are bite tender, 3-4 minutes.
  • Add the steak and juices back to the pan along with the coconut aminos. Toss all ingredients and cook an additional 1- 2 minutes until the liquid has evaporated.
