Quick Béchamel
On medium heat melt 2 tablespoons butter in a small sauce pan. Whisk in flour until it comes together into a roux. Add the milk in 1/2 cup at a time whisking to thicken before adding next bit of milk. When the entire mixture starts to thicken turn off heat. Stir in freshly grated nutmeg, salt, 1/2 teaspoon Dijon and 1/2 cup grated cheese. Set aside.
Heat remaining tablespoon of butter in skillet. Add spinach, garlic and a pinch of salt and sauté for about 5 minutes or until spinach is wilted and garlic has softened.
Assembly
Preheat oven to 350 degrees. Line a baking sheet with parchment paper
Cut each waffle into quarters. Butter each piece on one side only. Spread a very thin layer of Dijon on 6 of the slices on the opposite side (these will be the bottoms of your sandwiches). Sprinkle each slice with approximately 1/4 cup of cheese, top each piece evenly with spinach.
Place in the oven for ten minutes. Remove baking sheet from oven. Turn on broiler. Put the waffle ‘tops’ on the sandwiches then spoon enough bechamel to cover ( approximately 1/4 cup) Sprinkle with the remaining cheese.
Pop back into the oven for 2-4 minutes until top is golden brown and bubbly. * once they go under the broiler keep an eye on it so they don’t burn.
Fry 6 eggs sunny side up and place one on top of each sandwich.
