I've always loved breakfast casserole, but most of them are more bread than protein. Not this one! One serving (and I could only eat 1/2 a serving) has 140 calories, 12g of protein and only 3g of carbs.
1 1/2 cups ham (cubed or shredded)
6 oz plain Greek yogurt
1/4 cup crushed crackers (saltines/Ritz)
1/4 cup shredded cheese
2 tablespoons margarine
1 tablespoon finely chopped onion (I used onion flakes)
6 eggs
Preheat oven to 375 degrees. Spray an 8x8 pan.
Melt the margarine in a large bowl. Add the ham, yogurt, crackers, cheese and onion. Stir. Beat the eggs in a separate bowl, then stir into the first mixture. Bake for 20-25 minutes or until center is firm. Let stand before serving. 9 servings.
