• 23 pounds 95% Lean Ground Beef
• 2 cloves Garlic, Minced
• 2 Tablespoons Ketchup
• 1 Tablespoon Yellow Mustard
• 1 Tablespoon Worcestershire Sauce
• 1/2 teaspoons Steak Seasoning
• 4 ounces, weight Sharp Cheddar, Shredded
• 1 whole Egg Beaten With 1 Tablespoon Water For Eggwash
• 1 teaspoon Sesame Seeds
• 2 cups Chopped Romaine Lettuce (or Any Lettuce You Like)
• 1/2 cups Cherry Or Grape Tomatoes, Halved
• 1/4 cups Plain Yogurt
• 2 Tablespoons Mayonnaise
• 1 Tablespoon Minced Fresh Chives
• 1 whole Garlic Clove, Grated (or 1/4 Teaspoon Garlic Powder)
• 1 pinch Salt
• 1 pinch Black Pepper

1. FOR THE PIE:
2. Preheat oven to 375F and line a baking sheet with parchment paper.
3. Add oil to a medium saucepan over medium heat; once hot, add onion and cook until starting to soften, about 5 minutes.
4. Add beef and cook until brown*, then add garlic and cook 1 minute.
5. Add ketchup, mustard, Worcestershire, and steak seasoning and cook until the liquid is evaporated, about 3 minutes.
6. Cool completely.
7. Unfold puff pastry so that it forms a 9- by 10-inch rectangle (or roll it out with a light dusting of flour so that it forms a rectangle this size), and place it on top of a lightly greased baking sheet.
8. Spread the cooled meat mixture on the pastry (leaving a 1-inch border all the way around), and sprinkle the cheddar on top.
9. Lightly brush the border of the dough with egg wash (you will have extra egg wash) and sprinkle on sesame seeds.
10. Bake about 20 minutes, or until the pastry is puffed and golden.
11. Cool slightly before cutting, then top with lettuce, tomato, and a drizzle of Creamy Garlic and Chive Dressing.
12. *If you use meat with more fat than 95% lean, drain off the fat after browning.
13. **The steak seasoning I use contains sea salt, coarse-ground black pepper, coriander seed, mustard seed, dill seed, and red pepper.
14. It wont have exactly the same flavor, but in a pinch you could use a scant 1/2 teaspoon seasoned salt and 1/8 teaspoon black pepper.
15. FOR THE DRESSING:
16. Whisk together all ingredients; store refrigerated until serving.
