I bought one of those 400 ml soup tins from the supermarket the other day and mixed it with some fusilli pasta. I have a clay pot with a glass lid, it can go in the microwave or the oven. It came out very nice, like it was made in a restaurant. The vetables in the soup became part of the pasta and the spices in the soup merged with the it, the pasta absorbed all the water in the soup. There are so many different tinned soups, I tried the vegetable soup. Perhaps next time I can try the tomato one.
Cook pasta slowly in tinned soups, it works. You make a high quality pasta dish without doing much. I recommend lowering the power of the microwave if that is what you use. You can set the power of the microwave to 60% so the soup and pasta doesn't boil over. The lid traps most of the heat anyway.
