Dried fruit and honey sticks can be a quick source of energy. I also usually recommend mama's have things like nuts, nut butter, hard boiled eggs, yogurt and cheese handy since they are easy to eat sources of protein, but guess these are all out for you! Maybe some kind of jerky? It is easy to eat and has some protein in it. How about seeds, can you have pumpkin and sunflower seeds? Is it all dairy, or can she have goat products? There's a lot of variety of goat cheeses if that's a possibility. You could also try making a light protein shake with either soy or rice protein powder (whey is milk based), and just leave it in the fridge. I remember wanting sliced apples during my labors!
My favorite beverages for birth: Diluted 100% juice in your favorite flavor, diluted Recharge-similar to gatorade, but doesn't have that artificial, unsettling glow, and coconut water (not coconut milk) an excellent source of electrolytes and it doesn't have much flavor, you may want to try it first if you haven't ever had it, some people don't like the texture.
Hope that gives you some ideas, working around food allergies definitely makes it more difficult!!
