I was looking for ways to use up some things from the garden, and the fridge, and came up with some ideas for green beans-with a little help from the Net, as well.
Bowl of cleaned green beans, par boil or slightly steam, cool in ice water, to keep a bit of firmness. Take some major greys chutney, or mango salsa...add to this a dash of fresh lime juice (perhaps a bit of lime zest), finely chopped basil, or savory, and/or other herbs you like. Stir enough of the stuff into the beans to coat well. Garnish with some pine nuts.
I got to thinking about other options, such as: adding some finely siliced and cut red onion, black beans, or shoe peg or fresh corn.
Top off with your favorite dressing -- I like a vinegar and oil -- not many calories and if you make it using salt, pepper, a tablespoon of spicy mustard, a dash of pepper flakes and a tsp of cumin, and, if you like it hot a dash of jalapeno powder, it's mouthwateringly good!
I like to sauté some garlic in a little olive oil, then add a generous dollop of crunchy peanut butter, thinning it down with some soy sauce, rice wine vinegar, and if necessary a little water. Then add some hot chili sauce to taste but don't overdo it. Cool a bit, but while still warm mix with your cooked green beans. Then chill the whole thing for a while. Serve at a cool room temp.
We used to make a cold salad with leftover green beans or green and wax beans, basically a vinaigrette, but here's one I tried once and liked: a Belgian potato-&-green-bean salad in a book by, I think, Nika Hazelton. It's similar to a German potato salad but without bacon.
