Essential Ingredient Guide
- Fresh bell peppers: Choose firm, brightly colored peppers; they add sweetness and a crisp bite when roasted.
- Spinach: Rinse well and pat dry; it wilts quickly, so add it just before baking for a vibrant green.
- Cheddar cheese: A sharp cheddar gives depth; grate fresh for the best melt.
- Eggs: Provide structure; room‑temperature eggs blend more smoothly with the milk.
- Milk: Use whole milk for richness, or substitute almond milk for a lighter touch.
- Seasoned breadcrumbs: Sprinkled on top for a subtle crunch; toast lightly before using if you like extra crunch.

Ingredient Readiness:
Dice peppers, shred cheese, and whisk eggs with milk; this ensures everything comes together quickly.
