Make-Ahead Egg Muffin Cups

Preheat oven to 180°C (356°F). Spray a 12-hole muffin tin with oil.

Whisk eggs with salt and pepper. Divide spinach, pepper, cheese, and meat among muffin holes.

Pour egg mixture over fillings, filling each about ¾ full.

Bake 18–20 minutes until set and edges are golden. Cool, then refrigerate up to 5 days or freeze up to 1 month.
