I have no idea where I got this recipe from, but this is my go to quiche recipe. Usually, I use cream of celery soup instead of the broccoli and cheese, but really any cream based soup will do. It is great to be able to change it up at times. Maybe even change up the cheese. Sometimes, I even just mix the cheese into the quiche instead of just spinkling it on at the end. You can decide what is easiest/best. The recipe is simple and easy to use, so here you go.
Quiche
1 cup (divided) shredded cheddar cheese
6 eggs
1 can condensed cream of broccoli and cheese soup (or any other cream of soup)
2/3 cup milk
9 inch pie crust
If needed, pre-bake the pie crust at 425 for 10-15 minutes. Then set oven to 350. Spinkle the shell with 1/2 cup of cheese. Whisk together the eggs, soup, and milk. Pour into crust and bake for 1/2 hour or until set. Spinkle with remaining cheese and bake for 5-10 mins longer.
