This comes from the March issue of Glamour magazine, called the 970-calorie sandwich, a.k.a. the "Bad" 'wich.

Panera Bread's Sierra Turkey sandwich has a whopping 970 calories and 54 grams of fat (that's almost twice Burger King's Double Cheeseburger). Lesson: Turkey has a health halo, but it all depends on what it's paired with.

• Don't scrimp on veggies. If you do, you'll likely be loading up on other, fattier sandwich stuffings to feel satisfied.
• Beware creamy spreads. Fancy-sounding kinds can be calorie traps, like this chipotle mayo, which packs 320 calories and 34 grams of fat per serving.
• Watch meat portions. Panera got it right, but some delis pile on up to a pound of meat - that's enough for three people.
• Choose better bread. Watch out for oily, cheesy loafs like focaccia or ciabatta. These two slices set you back 510 calories!
