- Cook the spaghetti pasta by adding a few drops of oil and a little salt. Soak the pasta for 10 minutes and cook, this will give the best results and gets cooked soon. 
- Drain the water and cover it and keep it aside. Reserve 2 tbsp of the water before draining. 
- Finely chop the onions, celery, and capsicum. De-seed the tomato and chop them finely. Cook the corn kernels or you can use the frozen ones too. If using olives chop them into two. 
- In a pan add butter and oil and add the onions. 
- Cook till the onions turn pink and add the celery, capsicum, and tomato one by one. Cook for 3 minutes on medium flame. 
- Add the sweet corn and olives to this. 
- Add the tomato ketchup and the chili sauce. I used store-bought ketchup and chili garlic sauce. 
- Mix well and cook for a minute. 
- Now add the fresh cream and mix well. Add the cooked spaghetti to this. Add the reserved water which we kept after draining the spaghetti. 
- Mix evenly and add the oregano flakes to this. Mix again. 
- I didn't add any salt to the veggie mix. As the sauce has salt in it, I felt it is sufficient. 
- Only while cooking the spaghetti I added the salt. 
- Serve immediately.
