Heat oil in a large deep pan and sauté onions and garlic till soft and lightly brown. Add in spices and tomato paste, and fry for a few seconds.
Season with salt and add in the chopped tomatoes. Cook for a few minutes till tomatoes start to pulp.
Stir in ground chicken and let it cook covered for a few minutes, stirring occasionally, till chicken completely cooks through.
Mix in dried oregano and the veggies and cook for another 2-3 minutes.
Now toss in the pasta, and mix well to combine with the sauce. Garnish with fresh cilantro and serve warm.
