Walnut Mushroom and Bean Burgers

Walnut mushroom bean burgers

(Approximates as I was just using up what I had)

3/4 cup walnut pieces
10 button mushrooms, halved
Handful (20?) Greenbeans, trimmed
2-3 shallots / 1 small onion, quartered
1-2 cloves garlic, crushed
1 cup wholemeal breadcrumbs
1 Tablespoon miso paste (I used rice miso)
1 Tablespoon vegan worchester sauce
1 teaspoon thyme
....then to bind....
1 smallish steamed potato, peeled and smashed
2 Tablespoons vital wheat gluten

Put all first group of ingredients in a food processor and whizz until quite consistent texture. Transfer to large bowl with potato, mix together then sprinkle over gluten and mix that in last, with hands if needed. Shape into patties. This made 10 small patties. Could be put in fridge/freezer or cooked straight away.
Fry a couple of minutes each side to brown then place on ovenproof tray and bake at 180 for...some time while you look after kids / housework and just get them before they're too dried out! So, another 15 minutes? Check on them...
I used vegan mayo and Indian pickle for sauces but use whstever you think would go well. Something like a garlic vegan aioli or a smoky chipotle sauce or ajvar?
