When I was following a really strict allergy diet (not vegan at all, but absolutely no dairy even down to the long unpronouncables at the end of the list of ingredients), I personally preferred foods that were what they were supposed to be and not supposed to be like something else foods. Gluten free pasta, for instance, grosses me out. I'd rather do without. Use this time to go with a more whole foods kind of diet (if you can't tell what the food looks like in real life, don't eat it) and with some adjustment you'll be fine.
The thing with quinoa is it isn't like anything else. Start out using it in salads in small amounts and build up from there. You'll adjust and like it more and more. But while you're trying to tell yourself it's rice you're only going to be disappointed. Because then all you're getting is weird texture rice that appears to have gone bad
