When it's this hot out I often find it hard to turn on the oven or the stove, I just want something simple, fresh, and fast. A big thank you to Mark Bittman for putting together a list of 101 simple salads. Several of them feature cucumbers, which we're getting this week.
3. A nice cucumber salad: Slice cucumbers thin (if they’re fat and old, peel and seed them first), toss with red onions and salt, then let sit for 20 to 60 minutes. Rinse, dry, dress with cider vinegar mixed with Dijon mustard; no oil necessary.
21. Dice cucumbers (if they’re fat and old, peel and seed them first) and toss with cubes of avocado, a little mirin (or honey, but then it’s not vegan), rice vinegar and soy sauce. (You could mix in a little lump crab meat, really not vegan, even rice, and call it a California roll salad.)
23. Thinly slice some cucumbers (if they’re fat and old, peel and seed them first), red onions, radishes and fresh chili pepper. Soak for a few minutes in equal amounts vinegar and water, with some salt and sugar. When they taste lightly pickled, drain and serve, alone or over rice.
40. Slice cucumber and top with capers, olive oil, lots of pepper and little dollops of fresh ricotta. Note: cucumbers, ricotta and oil must all be really good.
