This is almost like the tinned spaghetti you can buy, except nicer and also because I have such a large family those tins just don't go far enough. I use double the ingredients and have some left over for toasted sandwiches.
1 packet of spaghetti, cooked according to instructions
1 440ml tin of tomato soup
2 tbsp condensed milk
mix all together in a large saucepan on medium heat until warmed through.
How easy is that. My ds14 made it tonight all by himself, he just needed help draining the spaghetti.
