Preheat oven to 400F or 200C.
Add cauliflower to a baking sheet or oven-safe dish. Drizzle with a little olive or melted coconut oil. Roast cauliflower until tender and crisp. This will take about 20-30 minutes. Or boil cauliflower until tender. This will take about 10-15 minutes. (FYI: sweet potato fries also go in the oven so if you have a small oven that can't contain 2 baking sheets, boil cauliflower instead)
Meanwhile, heat a skillet with a little cooking oil. Saute onion for 2-3 minutes, then add garlic, ginger, cumin, coriander, salt, and pepper, cook until onions are soft.
Cut sweet potato fries. Add to a baking sheet, drizzle with olive oil or melted refined coconut oil, and herbs. Toss to combine. Roast in the oven for 20-30 minutes. Toss half way to roast evenly.
When cauliflower is ready, allow to cool under running water.
Mash cauliflower and chickpeas. Add onion mix, lime juice, flour, and season with salt and pepper to taste.
Mix/mash well to combine. Make burger patties. Add more panko if too wet, or add a little water if too dry.
Cook burgers in a skillet over medium heat, turning until they are golden brown on each side.
Blend/mix sauce ingredients until smooth.
Serve burgers with a green salad, sweet potato fries and cashew sauce.
