Yes, tapioca starch should be ok.
I'd suggest nice fresh dishes eg...
Starters
Beef tomato and buffallo mozzarella
Shredded duck with leaves and sweet chilli sauce.
Mains
Stuffed peppers and/or veg roasted in the oven in olive oil with meat of choice.
Stuff a rainbow trout with veggies then wrap in foil and oven bake.
You could do a spanish style rice, put rice in a microwaveable jug and cover with water, add some turmeric (makes it yellow), season and stir then in the microwave for about 9 mins (watch there is enough water so it doesn't dry out and burn). You can also add things like lightly done peppers, mushrooms and courgettes.
