It's recommended that adults eat 5-7 servings of fruits and vegetables a day. One way to make veggies more enjoyable is to add a dressing to them just as one would to a salad. Once you have green beans dressed with butter, mustard, and a sour and salty garnish like cornichons, capers, or sour pickles, you'll never go back!
In a bowl large enough to hold the beans, melt the butter. Mince the cornichons, capers or pickles to about the consistency of a relish. Do not worry if the butter re-solidifies; the hot beans will melt it again.
Cook the beans and drain. Do not overcook the beans; they should still be bright green. Toss the beans in the dressing and serve.
