Below are the rough weights and types of veggies I use - but I tend to add whatever we have lurking in the bottom of the veggie drawer in the fridge as this is a good way to use them up.
Veggie Burgers
Makes 8 - 10 burger patties
1 tablespoon butter
200gm mushrooms, chopped
1/2 onion, finely chopped
2 cloves garlic, crushed
1 carrot, grated
100gm steamed broccoli
1/2 red capsicum, chopped
100gm unsalted raw cashews, finely chopped
1 package firm tofu (approx 290gm) - available in the chiller (fresh) at the supermarket or in the Japanese food aisle (long life)
Breadcrumbs from 2-3 slices of whole grain bread
1 tablespoon tomato sauce
Flour for coating burgers
Olive oil spray for frying
Melt butter over medium heat in frying pan, add chopped mushrooms and sauté for 3-4 minutes until they're just tender. Allow to cool slightly then transfer to food processor with remaining ingredients and blitz until well combined. If you don't have a food processor, you can do this by hand but will need to chop all the ingredients very finely before you mix them in a large bowl.
Form into 8 - 10 burgers around the size of the palm of your hand. Coat each burger lightly with flour before frying them over a medium heat until both sides are golden brown.
Freeze cooked patties by allowing them to cool and separating with baking paper and sealing in ziploc bags or an airtight container.
