pasta can also be tossed with pesto (basil sauce) or tapenade (olive paste) and a really simple alternative to tomato sauce is roasted red or yellow peppers: cut peppers in half, de-seed, put skin up on a lined cookie sheet, drizzle with olive oil and bake 'till some black spots start appearing. then puree for sauce (you can peel them before if you like, after baking, the peel comes off easily, makes a smoother sauce).
