I just got home from a couples cooking class, and we made a salad that would be very zone friendly for getting good carbs and fat with slight modification (not using currants). As an added bonus, it sits in a dijon vinagerette dressing, so the fruit marinates rather than browning.
You basically take 3 tart green apples, peel, core, and dice. You take 2 sweet potatoes, peel and grate. Roast some chopped pecans and add them in too. Throw 'em in a bowl and set aside.
Mince 2 cloves garlic, add to 2 tbls white vinegar, 3 tbls dijon mustard, add salt and pepper to taste, and add the juice of one orange and 2 limes. Whisk while adding about 1/3 cup olive oil. Throw over the fruit and chill for a half hour.
The acid in the vinagerette ends up breaking down the sweet potato, much like acid does with a dish like ceviche. The salad was absolutely delicious and trivial to make. Add some lean protein like chicken and you've got a great zone-friendly meal.
