Saw one in the Sunday Times a couple of weeks ago which was pesto, goats cheese and chilli. Been meaning to give that a try.
Sometimes when stodge is required and I have been too bone idle to do anything, simply spaghetti with olive oil and a load of parmesan is just right.
Nigella's stick pancetta and garlic olive oil in the oven for 20 minutes, then throw a load of linguine in it is good (plus parmesan as well).
Cheese and brocolli - cook the pasta, throw in some blue cheese and some steamed purple sprouting, and a little milk/cream/water to slacken it.
Easy puttanesca (not really comforting, very piquant), salted anchovies nd capers (wash the salt off), plus some black olives, tin of tomatoes and some chopped onion and garlic. Fry onion and garlic off, add all the other ingredients then whizz in a blender (not too much, want it chunky) and add to cooked pasta.
Or, for real stodge and comfort, my dd's tuna pasta bake. Cook penne, add tin of tuna and tin of sweetcorn, throw in tin tomatoes (or tub of tomato and mascarpone sauce), mix all together, put in oven dish, cover with crushed doritos (yes, really) and cheese on top then put in oven til bubbling. DD loves cooking this (I love it as well, means I can sit down and read Grazia)
