What kind of food should I expect on a Bhutan trek?

Bhutan is the only place where I've actually gained weight on a trek, thanks to the three meals a day (plus snacks) cooked up by trek staff. Breakfast is toast, cereal, coffee and often eggs. Dinner is a multi-dish feast of rice and vegetable curries; lunch is similar but cooked in the morning and transported in thermos dishes for a hot picnic. You'll even get French fries once or twice.
