Boil water in a pot, add salt to taste and 2 tbsp of olive oil, pasta (any variety) I used pipe. Cook until done about 15 minutes. Drain pasta, keep aside. You can reserve  some pasta cooked water incase if your pasta turns out dry you can add that instead of water.

Heat oil in a wok or pan, add oil then crushed garlic, sauté until nice aroma comes, then add finely chopped onions, sauté them well. Add ginger garlic paste, sauté well until raw smell goes, then add all the masala's, sauté well. Add diced tomatoes, salt as needed (remember that we have already added salt in pasta) mix well until nicely combined, cover the pan with lid, lower the flame and cook for 5 mins stirring occasionally.

When the tomatoes turn mushy, add finely cut green bell pepper, sauté well. Then add cooked veggies, mix well cover and cook for 5 mins in low  flame.

Finally add cooked pasta,mix well. Add grated Parmesan cheese, chopped coriander leaves, tomato ketchup. Mix well. Taste for salt if you want you can add more, also if your pasta seems to be dry, add the reserved pasta water and mix well.

Serve hot.
