2. A substantial salad

"I see people picnic with lettuce salad all the time, and I'm like, Guys, it's baking in the sun. Wilted salad is a picnic catastrophe! Bring more filling, grain-based salads--things like quinoa or farro are great. If you must do a green, go with kale. It's a hearty leaf, so it won't end up tragic."

3. Sandwich fixings

"Make your sandwich on-site, because soggy bread is a drag. Bring a baguette, a good cheese--Maggie's Round is the best--and a variety of ingredients so you can experiment with different combinations. I like Serrano ham with chives, but it's also good with blue cheese and pears--like, change-your-life good." (Maggie's Round, $17 per pound; artisanalcheese.com)

4. Something sweet

"Any kind of cookie is going to work really well; they're portable."

5. A versatile condiment
"For more mileage, choose one that has multiple uses. Pesto is delicious in a pasta or grain salad, and you can slather jarred caramelized onions on a slice of cheese or a baguette."

6. Planet-friendly flatware

"Go for fully biodegradable cutlery, made out of cornstarch, amazingly." ($6; vegware.us)

7. A tote bag
"It's nontraditional, but I carry my spread in a tote. You want to be nimble so you can do something fun after you eat. Who wants to be lugging a basket around?" ($56; yielddesign.co)
