When I was a kid, I LOOOOOOOVED it when my mother cooked up puffed rice and puffed corn in a pan with peanuts and raisins and chickpeas.
You start with a little oil, coconut oil might be really nice, add some salt and pepper and a little curry powder and then toss the chickpeas around, then add the peanuts and raisins and then the puffies. You'll need a rather big pan.
Popcorn is Vegan/GF. How about some popcorn balls?
Also, if you're feeling really ambitious, I made the yummiest apple tarts with crust made with Bob's Red Mill rice flour (recipe on the bag) and I used coconut oil instead of butter. I rolled the crust out and cut it in circles and put it in mini cupcake cups and baked a few minutes before putting filling in them. You could probably buy canned pie filling or even do veggie tarts with tofu and veggies in a blender and then bake. They would bake rather quickly.
Also, if you can find Glutino brand pretzels or pretzel sticks, they are delicious.
Sushi can be vegan, and gluten free. I haven't met a kid who doesn't like Inari sushi. It's those triangles that are made with tofu "skin" and stuffed with sushi rice. Also, if you can buy or make rice balls, my kids love those. I put a small amount of beans or pickled plum inside and roll a ball of rice around it and then roll the rice ball in some roasted and salted sesame seeds.
Chips and Salsa, Fruit kebobs, Hummus and veggie sticks/sesame crackers, baked tofu cubes (you can buy the tofu baked or do it yourself)....
You can also visit an Asian grocery store and you might get some really good vegan and gluten free ideas.
