obviously if you are diabetic, check with your physician).
Normally I would say get them at the Farmer's Market in the Summer when they are in season and melt in your mouth. Although for a special occasion like today, I think frozen berries are just fine. But don't even think about buying conventional strawberries, they must be organic. Strawberries are heavily sprayed and if you can't find organic you are better off skipping them altogether. But if you can find some, they're perfect for V-Day, they even look like little hearts.
Make a yummy smoothie, have them over a slice of vegan cake, make a raw strawberry cheesecake (bitt of raw is famous for her raw pies and I bet you can find a recipe or at least inspiring photos there, also rawmazing is a wonderful source for this sort of thing), eat them whole dipped in chocolate or plain. Strawberries not only look pretty and taste great, but they smell divine. A bowl of strawberries on the counter makes the whole room smell sweet and yummy and look at least as festive as flowers.
