I am sensitive to all of the above except for coconut & cranberries.
Rice noodles in a stir fries with veggies I can eat makes for a delightful dinner.
Smoothies make a grat snack! My fav is about ¾c raspberries, 8oz alternative milk of your choice, TB of sunbutter & 1TB of raw honey, then you can add a scoop of alternative yogurt to thicken or a half of a frozen banana.
I can eat beef as long as it’s grass-fed. In place of beef, I find black bean burgers with avocado on a gluten free bun to be tasty & filling.
My 7yr old son also follows the same diet, as he is also sensitive. He likes free range turkey & eats it daily for lunch. He prefers all foods to be cold. I use slices of turkey, DAIYA cheese (soy/dairy free) in the middle, roll it up & cut it into bites.
Since it seems you’re asking to prepare this for someone else:
Stuffed peppers would work if you filled them with a quinoa, bean & squash salad.
If you are looking for recipes, Forks over Knives or Engine 2 both list seasonal recipes that are easily modified to any dietary restrictions due to sensitivities/allergies.
