I swear I can eat everything in moderation, except tortilla chips. I love Tia Rosa thin chips - any really thin, restaurant-style tortilla chips, preferably unsalted. They're not really a "bad" unhealthy food, but I just can't stop eating them once I start.
My solution? I only buy about one bag a month. And I'm learning to eat veggies dipped in salsa to get my spicy fix.
