Prep the steak: Slice the leftover steak thinly against the grain. Let it sit at room temperature 10 minutes.
Pat dry and season lightly with salt and pepper if needed.
Choose your path: Tacos, Fried Rice, Salad, Pasta, or Sandwich. Gather the specific ingredients below.
Taco-Style Steak Warm a skillet with 1 teaspoon oil over medium heat. Sauté sliced onion and bell pepper with a pinch of salt until softened, 4–5 minutes.
Add 1 minced garlic clove, 1 teaspoon chili powder, 1/2 teaspoon cumin, and a pinch of smoked paprika.
Stir 30 seconds.
Stir in the steak and a splash of lime juice. Heat 1–2 minutes until just warmed through. Do not overcook.
Fill warm tortillas.
Top with salsa, cilantro, and a little shredded cheese or sour cream.
Fried Rice-Style Steak Heat 1 tablespoon oil in a large skillet or wok over medium-high. Add 1/2 cup sliced scallions and 1/2 cup frozen peas. Cook 2 minutes.
Push vegetables to the side.
Scramble 2 eggs in the empty space, then mix into the veggies.
Add 2 cups cold cooked rice. Stir-fry 3–4 minutes until hot and a little crisp.
