Tolkien's Elves appear to eat meat according to the earlier stages of the legendarium. From The Lay of the Children of Hurin, for example:
On a time was Turin at the table of Thingol there was laughter long and the loud clamour of a countless company that quaffed the mead, amid the wine of Dor-Winion that went ungrudged in their golden goblets; and goodly meats there burdened the boards, neath the blazing torches ...
The question might be: did JRRT change his mind with respect to The Lord of the Rings and later? For myself I do not think so. I see no reason to think that Legolas did not partake of all the 'flotsam and jetsam meal' for instance. And I think it's implied in The Fallof Gondolin (early 1950s version) that Voronwe and Tuor will eat meat in order to survive.
An argument might be made for the Green Elves of Ossiriand however: according to the Quenta tradition, the Nandor of Ossiriand heard that a lord of the Eldar from over the Sea was among Men, and they sent messages concerning these new folk, part of which included:
'And these folk are hewers of trees and hunters of beasts; therefore we are their unfriends,...'
But it was Finrod who had met Beor and his Men due to hunting with Maglor and Maedros, so if these Green Elves did not hunt, others did.
Of course I realize that hunting and eating meat are not the same thing, but for myself I would need some fairly convincing argument to split that particular hair.
Not forgetting that many Elves were hunters of beasts (aside from the creatures of Melkor), and hunting beasts for the sake of hunting alone, without the intention of eating them, would be a very 'un-Elvish' thing to do.
I was going to quote some of the instances of hunters in The Silmarillion but there are too many.
Although several instances in the text will strongly suggest Elves hunt and eat meat, as pointed out by Galin and mos, Elves do give off a sort of Buddhist, environmentalist vibe. I sort of picture them as tall, willowy model types. Despite the fact that they almost certainly do eat meat, I can relate to your mental image of them as vegetarians.
