Delicious Cream Sauce -pasta

This is the quickest most delicious pasta sauce that I have come accross. The recipe is something I saw on "Diners, Drive-ins and Dives". I just base the measurements roughly coz I didn't measure anything. Here's what you do:

Set water with salt to boil for pasta.

Chop quarter of an onion, 1/2 roasted red pepper.

In a pan with medium-high heat, add oil (abt 1-2tblsp). When the oil is hot, add onion and let it cook without stirring. 

Toss the pan or stir when onions start browning a little bit, add half and half (which is what I had but use cream , milk etc.) (about 3/4 c) and any bottled marinara or Ragu (abt 1/4 to 1/2 cup). Mix well and add the roasted red peppers. 

If you added milk, you can also add some béchamel if you have any to thicken it. Add salt and pepper to taste. The Ragu I added tasted a little sour so I added about 1 tsp of sugar too. Stir well and it should thicken a little bit. 

By this time pasta (I used raviolis) shoul be done. Drain and add to the sauce. Add some parsley on top (can be skipped)

Grate some fresh Parmesan and serve! Yummy!

This is so delicious but at the same time quick! By the time pasta is done, this sauce is done as well!
