1. Place tomatoes in the jar of a blender; blend for 15 seconds and set aside.

2. Heat oil in a large saucepan over medium heat; add shallots and garlic and cook until soft and lightly browned, about 15 minutes. Add salt, mint, basil, oregano, black pepper, and red pepper flakes; stir to combine. Add tomatoes and 2 cups water; bring to a boil, and immediately reduce to a simmer. Cook for 45 minutes.
