lazy girl shortcut: ketchup

Wanna know a lazy girl shortcut I take? Almost invariably when a recipe calls for tomato paste, unless it's a large amount, I just squirt in some ketchup. I got used to using those Amore tubes of tomato paste, and when Smith's stopped selling them I just couldn't face going back to the cans. And ketchup works just fine. Don't tell anyone, but it doesn't even have to be Heinz. I use Muir Glen. Shh!
