In a small bowl mix together the following: onions, salt, black pepper, dried oregano, paprika, red chili flakes, mixed herbs, vinegar, sriracha/hot sauce, tomato paste and bell peppers. Keep it aside (this step will save time).
In a wide pan over medium high heat, add oil, minced meat of your choice and the ginger garlic paste.
The mixture will release water. Cook until the mixture almost dries up (but not completely dried up!).
Then add all the ingredients you had gathered in the small bowl.
Cover and lower the heat slightly and cook until the meat mixture is almost done.
Once done, remove from the heat let the mixture cool completely.
Once cooled, add in the diced tomatoes.
