Drizzle each bowl with creamy provolone sauce. Sprinkle each bowl with fresh parsley.
Serve immediately.
Notes
Tips and Tricks
Slice the steak thin - Thin steak cooks faster and stays easier to chew. If the steak is hard to slice, chill it in the freezer for 10 to 15 minutes first.Do not crowd the skillet - If the steak overlaps too much, it may steam instead of brown. Cook it in batches if your skillet is not large enough.Use warm rice - Warm rice helps the cheese soften and keeps the whole bowl at a better serving temperature.
Storing and Reheating
Store in Refrigerator - Place leftovers in an airtight container. Refrigerate for up to 4 days.Store Sauce Separately - Keep the creamy provolone sauce in a separate container if meal prepping. This keeps the rice and steak from getting too wet.Reheat in Microwave - Place one serving in a microwave-safe bowl. Heat in 30-second intervals, stirring between each interval, until warm.Reheat in Skillet - Place steak, vegetables, and rice in a skillet over low heat. Add 1 to 2 tablespoons water and stir until warm.Add Sauce After Reheating - Warm the sauce for a few seconds in the microwave, then drizzle it over the bowl before serving.
