According to Chipotle's nutrition calculator, there are about 800 calories in one chicken burrito bowl, as well as 34.5 grams of fat, 46 grams of protein, and 75 grams of carbs. But keep in mind that's if you eat the entire thing as one serving. If you get two meals out of one burrito bowl, that's half the calories and nutrients per serving. A benefit of making these at home is that you can better control the calories and ingredients.
