If you make this according to the recipe, each chicken burrito will contain 337 calories. For a lighter version, avoid using sour cream. Instead, substitute Greek yogurt mixed with a squirt of lime juice. You can also reduce the amount of cheddar cheese by a third or even half while adding a little grated parmesan to boost the flavor. And instead of Spanish rice, try using steamed white or brown rice to keep the heartiness while cutting out calories. Adding salsa or hot sauce are great ways to cut calories without sacrificing that authentic Mexican flavor.
