Step-by-step
- Marinate the sliced tomatoes in a bowl with the rice vinegar and soy sauce, sugar, onion, chilli and ginger for at least 30 minutes.
- Mix the herbs with the butter or oil and spread over the top of the mushrooms. If you’re cooking indoors, preheat the oven to 180°C (350°F/gas mark 4). Place the mushrooms on a baking sheet and roast for 10–15 minutes. If you’re outdoors, cook them on your plancha or on the bars of the grill over the direct heat.
- Meanwhile, stick a frying pan on a low heat on the hob (or over a less hot part of the grill), add a little butter or oil and lightly fry the garlic and chilli, until the garlic goes golden – a minute or so.
- Now toss the spinach into the pan with a tablespoon of water. Throw a lid or baking sheet on top of the pan and sweat the spinach down. Stir a couple times. It won’t take more than 2 or 3 minutes. Season with the salt and pepper.
- When the mushrooms are cooked, get ready to assemble your burger. First, toast your buns. Place the mushroom onto the base of the bun. Top with the wilted spinach, a couple of slices of the soy tomato and the top of the bun.
