The healthiest fast food lunch option

#1 Panera Bread
Over 1,230 locations nationwide (and in Canada)

This bakery-cafe-based eatery wowed our judges with a comprehensive menu of healthy choices for every meal. “Variety makes it easy for everyone to choose healthy,” praises registered dietitian and panelist Marisa Moore. What does that mean for you? For starters, you can pick from two whole-grain breads for your sandwich and have an apple with it instead of chips (though the chips are fine, too—they can be baked!). Half-size soups, salads, and sandwiches make it a cinch to control portion size. Also, most of the chicken is antibiotic- and hormone-free, a rarity for large chains.

Panera also won top honors for kid fare, dishing out RD-approved crowd-pleasers like squeezable organic yogurt, PB&J (with all-natural peanut butter), and grilled organic cheese on white whole-grain bread.

We love: Delicious, nutrient-packed combos like a half–Turkey Artichoke on focaccia bread with a bowl of black bean or garden vegetable soup.
Danger zone: Sticky buns and cheese danishes are on display at the counter.
