Tips and Tricks
Slice the steak thinly - Thin strips cook quickly and are easier to divide evenly among the bowls.Cut evenly sized sweet potatoes - Keeping the cubes close to ½ inch helps them roast at about the same rate.Give the steak some room - A crowded skillet can make the steak steam instead of brown. Cook it in two batches if your skillet is smaller.Keep the sauce separate for meal prep - Add it after reheating so it stays cool and creamy.
Storing and Reheating
Refrigerator - Store the sweet potatoes, steak, and vegetables in an airtight container for up to 4 days. Refrigerate the sauce separately.Microwave - Reheat the steak, vegetables, and sweet potatoes until hot, then add the cold fajita sauce.Skillet - Reheat the steak and vegetables over medium heat until warmed through. The sweet potatoes can be reheated in the same skillet or separately.
