An easy, breezy salad to go: Tabouli.
Start with Bulgur wheat. Buy a package like this one, not a skinny one with spices and stuff you don't want.
Follow the instructions on how to cook and cool the wheat.
Chop up any greens you have. This is my stash today: cucumbers, tomatoes, mint, parsley, red onion, lemon zest, young radishes.
Some days though, I might have more parsley than mint, more arugula than tomatoes.
Dress with lemon, olive oil, salt and pepper, a touch of cumin.
Refrigerate for at least an hour.
If you want to make a salad to go on a picnic, this is your best choice, I think.
