Game Hen and Grapes. Kate tested and approved this delicious, super-easy recipe for Roasted Cornish Game Hen and Grapes from Martha Stewart OmniMedia. Budget some fat grams and splurge. They don’t include the counts, but roughly it works out to be: Calories = 550, Protien = 29g, Fat = 33g, Carb = 34. Portion: 1/2 hen (with skin), 1 cup grape/shallot mixture. It’s satisfying! Unusual and pretty enough for company. We served it up with a big green salad.
