Mix the ingredients meant for white sauce.
Boil the pasta in a big vessel to which 1/2 tsp salt has been added. Boil it aldente. Drain the pasta after boiling, but retain the water. I used Barilla Fusilli pasta.
On the other side, in a pan, add olive oil and fry the chopped onions. When the onions turn pinkish, add garlic. Fry for another 2 mins by keeping the container covered.
Then add chopped tomatoes and fry till tomatoes turn mushy.
After this add the broccoli and toss for sometime. Keep the pan covered for 10 mins.
Now add olives.
Add the tomato sauce.
Add the white sauce.
Add the boiled pasta and toss it in the cooked veges. Add salt to taste.
If pasta gets too dry, add little water in which the pasta was boiled.
Add grated cheese.
Top it with Italian seasonings and chilly flakes.
Note:Boil the pasta and prepare the veges simultaneously. So as soon as the veges gets cooked and sauces gets added add the drained pasta. The boiled hot pasta absorbs sauce and flavours better.
