  • 1/4 cup green pepper, chopped
  • 1 cup grated Parmesan cheese
  • salt and pepper to taste

  4. Add mayonnaise, chopped onion, chopped green pepper, grated Parmesan cheese, salt, and pepper to the eggs and mix well.

Tips & Substitutions

For a creamier texture, consider adding a bit of cream cheese to the mixture. If you're out of Parmesan cheese, you can substitute it with cheddar or mozzarella for a different flavor profile. To enhance the dish, try adding fresh herbs like thyme or basil. Make sure the squash is well-drained to avoid a watery casserole.

Serving Suggestions

This casserole pairs wonderfully with a fresh garden salad or crusty bread. It can also be served as a delightful side dish alongside grilled meats or roasted vegetables. For a more substantial meal, consider pairing with a protein like grilled chicken or fish.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F (175°C) for about 15-20 minutes, covered with foil to retain moisture, or microwave individual portions until heated through.
