Why, make French Toast with them!
Croissant French Toast Ingredients:
1/4 cup of milk
Splash of vanilla
I sliced the croissants into thirds or fourths, dipped them briefly in egg/milk/vanilla batter, and cooked on a hot pan. It really smelled amazing. I offered it to Babyface and he loved it. I froze the leftovers and they reheated just fine in the toaster oven on low.
