I had a can of Mezzetta Tomato Basil sauce in the cupboard which is almost as good as what I make myself so I defrosted, peeled and tailed a bunch of prawns to go in it. I put the pasta on to cook and started sweating a diced shallot. When the shallot had a little colour I added the prawns with some salt. I turned them over quickly and did the other side being careful not to overcook to prawns. I poured the sauce out of the jar over the prawns and heated it up. When the pasta was ready, plate pasta, sauce and garnish with fresh grated parmesan.
It was good, the prawns weren't particularly flavourful but they weren't objectionable either. If I have running water but don't want to cook or go out, this is an excellent alternative.
