When: Saturday - 3pm

Where: Watching the pros

No matter how hungry you are, stay well clear of the nutrition/hygiene disaster zone of the burger van. If you can't wait for a healthier fare, at least go for a hotdog (334kcal) instead of a burger (562kcal). That saves 228 calories and reaching for mustard over mayo shaves another 59. Get the vendor to hold the greasy fried onions too.

You put away: Hotdog with mustard

You save: 287 calories
