We visited my mum for the weekend recently and as always she filled her house with vegan treats and then sent us home with everything we hadn't eaten - which was mountains of it.
Fry and onion and 3 large chopped mushrooms. Add a mug of freshly ground mixed nuts, 2 mugs of breadcrumbs and a handful each of pumpkin seeds and pine nuts. Mix in a jar of pasta sauce (and maybe some water to get it all wet enough) then press the mixture into a dish. Cover with more pasta sauce and sprinkle with sesame seeds. Bake for a good old while.
I'll check the quantities with her but she's probably forgotten too. She cooks intuitively rather than from recipes and her food is always amazing.
