Step 1

Add all of the ingredients in a food processor and blitz. You may need to stop and scrape off the sides a few times. It's best to keep it course, you don't want a puree. Taste the mixture to check to season and add more salt/spices if necessary.

Step 2

Refrigerate for about 15 minutes. This helps it firm up a little and makes it easier to shape the burgers.

Step 3

Shape into 4 patties, pressing them together really really firmly then using the palm of your hand press down on the top of each one to make it a burger shape. If they crack a bit just press them gently back together.

Step 4

Place the burgers on a lined baking tray with parchment paper and bake them in the oven on 375°F/180C until heated through and a bit crusty on the outside (about 25 minutes).
