The only thing that rivals America’s obsession with sports is its passion for eating. So it’s no wonder that tailgating has become a national pastime. Stadium-adjacent parties have progressed from bags of pork rinds and cold sandwiches to sophisticated buffets with everything from rack of lamb to wheels of brie. Yet the typical cooking style is still grilling, which means pregame festivities continue to be ruled by dogs, burgers and sausages -— along with their related sides and suds. While these mouth-watering foods can justify sitting through even the dullest of games, they’re also usually landmines for fat, sodium and calories. But with some careful shopping and prep work this football season, you can keep your midsection tighter than a Peyton Manning spiral.
