There's a place in my heart and cupboard for a certain amount of convenience food.
I buy and use: Kraft singles, canned frosting(the spreadable kind), baking mixes of all kinds, refrigerated cookie/sweet roll/cresent/etc dough, hamburger helper, Kraft mac and cheese, individual packs of pudding and applesauce, sandwich cracker packs, frozen veggies, frozen waffles/bagels, frozen pizza(including pizza rolls), frozen chicken patties/nuggets, steakums, and more.
Of course, I only buy those things when they are on a good sale and I have coupons for them. Well, excpt for the Kraft singles and the mac&cheese. I must have those in the house at all times, price be damned!
I draw the line at things that are just crazy such as the aresol pancake batter and peanut butter singles. That is just too much. They already sell pancake mix in a jug so all you have to do is add water, shake it up and pour it out. And if you are unable to spread peanut butter on bread, you need to get some serious help.
