First off, in Canada we don‘t have Meals Rejected By Ethiopians, we have IMP‘s... they consist basically of an entree, a dessert, coffee/tea, a cold beverage, and snack (gum with breakfast, chocolate bar with lunch, and cookies with dinner). It‘s generally not bad food, actually... some things aren‘t great but individual tastes vary.
As for on the base... The food at the BARFF (Base All-Ranks Feeding Facility) is varied and generally not bad at all at Gagetown, at least.
