You are awesome for helping out your friend in this way.

If your friend is sick, the last thing she needs is over processed stuff like some mentioned below. Lots of fresh veggies, beans, whole grains are great. If you wash several bunches of kale for her and tear them up and put them in a ziploc baggie, she can grab a bunch, put it in some water and lightly steam up to have fresh veg each day filled with vitamins and minerals (including calcium) Brown rice and quinoa, once cooked will store for days in the fridge as will some beans. Kidney, lima, pinto, chickpeas all different vitamins and minerals in them will really pick her up.
