Burger toppings are the key to delicious burgers. And veggie burgers are no exception. To make the cauliflower burger so yummy, I chose simple but tasty toppings and I assembled the burger as follows: - I covered the bottom bun with a generous layer of avocado lime spread. - I topped the patties with red cabbage. - I drizzled with ranch dressing - use this one or make your own homemade ranch dressing here. Just add the top bun and dig in!
