We have a glut of them as usual despite only having two plants. They don't freeze very well. Except perhaps as a mush for a soup.
Include them in a potato gratin, a quiche, any stew. To smuggle them into food for the grandchildren, grate them into fritters, Bolognese. Cut into chip shapes along with peppers and aubergines, fried with onion and simmered for a while in tomato sauce. Hey presto, ratatouille. Can be the main dish or an accompaniment.
Just lightly boiled and tossed in butter go well with fish, chicken or even the Sunday roast.
Pick them while they're small and sweet and just eat them raw. Our local restaurant mixes them into salads, cut julienne style.
Halved lengthwise and stuffed. Either with a mincemeat farce or a veggie version. I had a recipe once which stuffed them with feta, sweet corn and chopped walnuts.
I could go on...
