+# Optimized Beef and Onion Stir-Fry Recipe
+
+## Beef Cut Guide
+Choose one of these cuts for your stir-fry:
+1. Flank steak: Often considered the best for stir-frying. It's flavorful and becomes tender when sliced correctly against the grain.
+2. Sirloin: Particularly top sirloin, which offers a good balance of tenderness and flavor.
+3. Ribeye: For a more indulgent version, ribeye provides excellent marbling and flavor.
+4. Tenderloin: If you prefer a very tender cut, though it's more expensive.
