Sautéed flank steak and peppers with onions FAQ:

What is the best way to know if the flank steak is cooked to my liking?

Can I store leftovers, and if so, how?

Yes, you can store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, use a skillet over low heat to avoid overcooking the steak.

What can I substitute for flank steak in this recipe?

You can substitute flank steak with skirt steak, sirloin, or even chicken breast. Adjust cooking times as needed based on the thickness of the meat used.
