HAM SWISS BREAKFAST CASSEROLE

We love doing breakfast for dinner or making this casserole when we have guests in town. It’s easy, cheesy, and full of flavor!

INGREDIENTS

• CROISSANTS – These can be found in the bakery or deli section of your grocery store. Crescent dough from the can cooked does not yield the same result.
• HAM – I prefer a diced ham from a ham steak or cooked ham. I don’t love deli ham (like for sandwiches) as much but it can’t be used.
• SWISS CHEESE – I love the flavor this gives the casserole but Gruyere, cheddar, or Monterey Jack cheese can be used.
• EGGS
• DIJON MUSTARD – This adds a special flavor and tang to the dish.
• HALF AND HALF – You can use milk or all cream if you want.
• GREEN ONIONS
