How do I scale Savory Cheddar & Jalapeño Omelet for a different number of people?

The recipe is written for 1 servings. Multiply each ingredient by (your serving target / 1). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
