method (tick as you go)
Preheat your oven to 200C (400F).
Cook burgers according to packet instructions.
Assemble burgers with kale on the bottom, tzatziki, red pepper and red onion on top.
You can whip up your own vegan tzatziki using dairy-free yogurt, diced cucumber, a little garlic and olive oil. Season to your own taste with salt and pepper.
Assemble, and enjoy!
