My No. 1 summer essential.

Last Friday, my house was a flurry as my three roommates packed and readied for jaunts abroad: Jason to Greece, and Michael and Greg to Spain (expect a guest post from Michael upon return). Not wanting to add to the confusion, I planned to spend most of the day out of the house. Instead, I spent the late morning and early afternoon at our kitchen table, a big old farm-style table we salvaged off Craigslist from some guy in the East Village years ago. It's the center of our home, and from my seat on Friday I enjoyed watching my friends pack their bags, exchange travel tips and leave me detailed instructions on how to care for our many plants. Around 1 p.m., we were all a little hungry, and Jason wondered aloud if he should leave early to have lunch out. Knowing we had more food than I could possibly eat myself, I told him to go out for some beer and that I would make lunch.

Quick and easy lunches are almost as good as long leisurely ones; they certainly can be as restorative and satisfying. As always, I like to seek inspiration from my favorites: Chez Panisse in Berkley (love the new Web site), Le Languedoc on Nantucket, Mass., and Blaue Gans here in New York. Friday, I prepared for ours by boiling a few eggs and putting together a cheese platter with some aged cheddar and feta. Next, I washed some lettuce from our CSA share, chopped a garlic scape and a handful of raw almonds, and mixed an oil and vinegar dressing. Finally, I tossed some leftover spaghetti with marina (I didn't even bother reheating it) with some extra-virgin olive oil, balsamic vinegar and red pepper flakes. So it was a little more Italian than French or German, it was still delicious and a nice way to say "bon voyage."

While recounting the afternoon to a friend yesterday, I realized none of it would've been possible without a few staples, the things I can't cook without. My list of must haves is short: good coffee, extra virgin olive oil, a handful of vinegars (I like this white wine vinegar from Zingerman's in Ann Arbor, Mich.) and lemons. With these four things in my possession, I feel like I can conquer the world, or at the very least entertain a few hungry stomachs. Of course, actual food is required to do the latter, and what's in the house varies depending on season. For now, it's loads of gorgeous produce from Garden of Eve Farm, like bok choy, frisée, kale, lettuces, cucumbers, dill, garlic scapes, summer squash and this thing:

That's kohlrabi, and it's not as scary as it looks. But until I decide what to do with it, I'm sticking to what I know best.

The only salad dressing you'll ever need (really)

So fresh and simple, a nice oil and vinegar salad dressing will allow for quality produce to speak for itself. And the best part is, variations abound: olive oils and vinegars range from sweet to spicy, and fresh-squeezed grapefruit or lime juice can easily replace the lemon. Chopped herbs or cheese (a crumbly blue or feta works well) can be added for texture.

Ingredients
