One of my favorite lunches when I take a lunch break at work is Chipotle. I like the food, I can have a good low carb meal, and the quality of their food is higher than many other choices.
My selection at Chipotle is typically a salad with no rice and no beans, with steak, grilled peppers and onions, sour cream, cheese, and guacamole and a little hot salsa. The macronutrient content of this meal is very good. There are minimal carbohydrates, moderate protein and high fat. Just what I'm looking for.
From a quality standpoint, Chipotle is above average in my opinion. They use grass feed beef and there doesn't appear to be a lot of additives, etc. in the other ingredients, and they avoid foods ("whenever possible") with antibiotics and hormones. They do use vegetable oils for cooking, although, while they use sunflower oil for things like their chips, they say they use "rice bran oil" for their steak. While the rice bran oil has a lot of Omega 6 polyunsaturated fat which is not good, it has quite a bit of monounsaturated fat which is good. At least it avoids the downsides of soybean oil.
With the vegetables, grass fed beef, and hot salsa, there are good micronutrients. The downside is the cheese and sour cream which is unlikely from grass fed cows, and the fact that I usually have a diet soda with this meal, that takes off a few points.
