I'll add in my two cents. (great topic, by the way, especially considering in light of the holiday weekend I've probably consumed about 100 cookies, 6 hamburgers, 19 hotdogs, 8 pieces of pizza and about 600 pieces of homemade caramels) .............. anyway, here's my favorite "junk" foodS. Yeah, baby, you saw that, PLURAL. Foods!! hahahahahaha.
Heath candy bars (could there be anything better?)
Lemon bars (must be homemade)
Ham and Scalloped potatoes (my mother-in-law's recipe, guaranteed to have about 6 sticks of butter in it and gallon of whipping cream)
Twizzlers (duh)
Caramel Bugels (recently discovered these at the vending machine at work, yes, food can talk to me and these babies talk to me often!)
Starbucks raspberry Italian Soda (while probably not the worst thing I could get at starbucks, these definitely aren't healthy either, but ohhhhh what a guilty pleasure!)
Tortilla chips with a touch of lime (I'm reminded of the little sign my aunt has by her front porch whenever I eat these chips. It says, "It's 5 o'clock somewhere" and shows a picture of a margarita. These chips and drinks are like a hand and a glove, peas and carrots, ... well, you get the idea)
Anything ice-cream related. (And I do mean anything. Blizzards. Ice cream cones dipped in chopped peanuts. Frozen Pies. DQ ice cream cakes. Man 'o man. Ice cream was the reason I gained 50 pounds during my first pregnancy ... haha)
And I could go on and on. But I'll stop now.
