I had some broccoli and carrots wilting away in the fridge, desperate to be used, so they went in, along with a few very finely sliced and de-strung runner beans.
First, take a load of new potatoes and put them in boiling water to cook, with the rest of the veg chopped up in a steamer over the top. Separately, fry up a purple onion (I'm not a fan of steamed onion!).
While those are cooking, whizz up some breadcrumbs and lay out three plates, one for flour, one for a beaten egg and one for the breadcrumbs - to coat the burgers with.
When the veg and potatoes are cooked, mash them with some butter, pepper, a little milk and salt if needed. Mix in the vegetables and form into patties, then coat them first in the flour, then the egg and finally the breadcrumbs.
Heat up some oil in a big frying pan until it's really, really hot, then put the burgers in and let them cook without moving them for a few minutes. When the breadcrumbs around the side start to turn brown turn them over and cook for a few more minutes.
Serve with some melted cheese and tomato ketchup, they went brilliantly with sweetcorn but it would have been lovely in the mixture too.
