You know.. I don't think there's a vegetable that I've met that I haven't fallen in love with.
On a daily basis I like to go with heartier leafier greens such as kale that are eaten raw or really quickly pan cooked, braised, oven roasted, stir fried, for at least one of my meals, and brightly coloured tubers, Adirondacks/all varieties of sweet, etc., but always always will eat for the season. Right now a lot of sweet little new tubers - the size of your thumb!, zucchini, beets, avocado, fennel, and really cool heirloom lettuces. Deers Tongue is crazy good.
I'm an equal opportunity veggie eater :)
Roasted asparagus, roasted brussels sprouts, any greens sauteed in bacon fat with lots of garlic, lemon juice, zest and sea salt, eggplant prepared almost any way....lately though, I eat mostly Zucchini and lettuces from my garden!
