Preheat the oven to 450 degrees F. Line a rimmed baking sheet with parchment paper.
In a medium bowl, combine ground beef, garlic and half the fresh spices/herbs and salt. Using your hands, mix together until well combined.
Add the beef mixture to the baking sheet and flatten into a round, thin circle. Wrap a wooden rolling pin with parchment paper and gently roll out the meat. Try not to tear the meat.
Bake the crust for 10 minutes.
Remove the baking sheet from oven. Use a paper towel to soak up the juices before flipping the crust.
Reduce temperature to 350 degrees F. Bake an additional 10 minutes.
While the pizza crust is baking, stir together tomato paste and water.
Remove the pizza crust from the oven. Top the pizza with tomato paste mixture.
Sprinkle over bell peppers, red onion, and mushrooms. Return to the oven for approximately 5 to 8 minutes, until the vegetables are crisp tender. Sprinkle with remaining fresh herbs. Serve immediately.
– If you like a little heat on your meatza, sprinkle the meatza with 1/4 to 1/2 teaspoon of red pepper flakes.
