Ooh, food!
Try some of these. They're all recipes that use edible flowers, and while some of them are definitely not what you're looking for (the salmon and the chicken ones in particular), you've still got some possibilities here, like curried daylillies and strawberry mousse in tulip cups. Flowers in general are pretty easy to look up if you want some inspiration because you can find a lot of real-life recipes online for them. (As in, if no ideas suit your fancy here, you can pretty much Google a flower and the word "recipe" and come up with what people have actually done.)
Lemongrass is also something you might be interested in, but you'll want to be careful and make sure you specify that you're looking for vegan or vegetarian recipes. Otherwise, you end up with a lot of chicken and fish. (But if you'd like a suggestion, you could go with lemongrass gyoza or, for something not on the site,
mushroom lemongrass soup.)
If that doesn't work, you could always try looking up the fanciest restaurant you know. A lot of restaurants have menus online these days, so that makes it easy for you to check one out and see what kinds of things you'd normally find on a menu. You'll probably find out that dish names are usually not as fancy as the price would make them seem, so it's okay to go with an ordinary-sounding name so long as the food sounds tasty.
