(from castro15’s recipe box)
Categories: Meals
Ingredients
- 1 Red Onion
- 2 clove Garlic
- 1 tablespoon Tomato Paste
- 5 teaspoon Balsamic Vinegar
- 20 ounce Ground Beef
- 1 cup Mozzarella Cheese
- 4 Ciabatta
- 8 ounce Heirloom Grape Tomatoes
- 4 ounce Spring Mix Lettuce
- 2 ounce Dried Cranberries
- 10 teaspoon Olive Oil
- 2 teaspoon Sugar
- Salt
- Pepper
Directions
-
Wash and dry all produce. Preheat toaster oven or oven to 400 degrees. Halve, peel, and thinly slice onion. Heat a drizzle of olive oil in a large pan over medium heat. Add onion and 1 tsp sugar. Cook, tossing, until browned, 6-8 minutes. Season with salt and pepper. Remove from pan and set aside.
-
While onion cooks, mince or grate garlic until you have ½ tsp (you may have a clove left over). In a large bowl, whisk together ½ TBSP tomato paste, 1 TBSP vinegar, 1 TBSP olive oil, and as much minced garlic as you like (we sent more tomato paste and vinegar than needed). Season with salt and pepper.
-
Wipe out pan used for onion. Heat a drizzle of olive oil in it over medium-high heat. Shape beef into 2 patties slightly wider than the bread. Season with salt and pepper. Add to pan or grill. Cook until just shy of desired doneness, 2-4 minutes per side. Sprinkle mozzarella on top. Cover pan or grill and cook until cheese melts, 1 minute more.
-
Split ciabattas in half. Toast in toaster oven or oven until golden, 3-5 minutes. Meanwhile, halve tomatoes lengthwise.
-
Add lettuce, tomatoes, and cranberries to bowl with vinaigrette and toss to combine. Season with salt and pepper.
-
Fill ciabattas with beef patties, onion, and a few leaves from salad. Divide between plates and serve with remaining salad on the side.
