Dinner Quiche

1 refrigerated pie crust (from a 15 oz pkg)
1 lb ground beef
1/4 cup ketchup
1 Tbsp Worcestershire sauce
1 medium red onion, diced
2 packed cups baby spinach
1 cup grape tomatoes, halved
1/4 tsp salt
1/4 tsp pepper
5 large eggs
3/4 cup milk
2-3 Tbsp Dijon mustard
1 cup shredded cheddar cheese

1. Heat oven to 400°. Unroll crust and roll out slightly. Fit into the bottom and up the sides of a 9 inch deep pie dish. Flute edge. Line crust with nonstick foil. Bake @ 400­° for 12 min. Remove foil.
2. Meanwhile, cook beef in a large nonstick skillet over medium-high heat, 5 min, breaking apart with a spoon. Spoon into a bowl and stir in ketchup and Worcestershire sauce.
3.In same skillet, cook onion for 5 min over medium heat. Add spinach and tomatoes; cook 3 minutes. Season with 1/8 tsp each of the salt and pepper. Stir in beef.
4. Transfer beef mixture to crust. In medium bowl, whisk together eggs, milk, mustard and remaining 1/8 tsp each salt and pepper. Sprinkle cheese over filling. Carefully add egg mixture. Bake @ 400° for 35-40 minutes. Let stand 5-10 minutes before slicing.

The original name for this was Cheeseburger Quiche, but that sounded a little too scary for me so I liked Dinner Quiche better! It was a big hit with everyone and the only change I made was I used diced tomatoes instead of grape tomatoes. And next time I will bake it on a cookie sheet, we had some bubble over into the bottom of the oven...ick.
