Super cheap if you tend to keep garlic and olive oil on hand at all times like I do and can find a can of clams for more like $0.99 instead of $2.50 (luckily, I can at one of the cheaper grocery stores). If not, it's still worth it. I keep parsley frozen flat in the freezer and just break off a piece to add, but you can go with anything along the lines of the basil, Italian seasoning, parsley family, really - very versatile that way. Mix and match spices or even oils, add milk or don't, and it will still be delicious and fast. Aiming for healthier? Excellent over whole wheat pasta, too!
