Can I make these ahead and freeze them?
Yes. Assemble the egg rolls, place on a parchment-lined tray, and freeze unwrapped for 2 hours, then transfer to a freezer bag. Fry from frozen, adding 1–2 minutes to cook time.
What cut of steak works best?
Sirloin or ribeye sliced very thin (partially frozen steak is easiest to slice). Avoid tough cuts; the meat cooks briefly, so tenderness matters.
How do I prevent the filling from leaking during frying?
Don't overstuff—use about 2–3 tablespoons per roll. Seal the wrapper corners tightly with water, and ensure the steak and peppers are dry before filling.
Can I bake instead of fry?
Yes. Brush with oil and bake at 400°F for 12–15 minutes until golden and crispy, turning halfway through. Results are lighter but less crispy than frying.
What's a good substitute for provolone?
American cheese, cheddar, or pepper jack work well. American melts fastest; pepper jack adds heat.
