Good news: the cauliflower quinoa burger can be made ahead of time. I’m talking about the quinoa cauliflower patties because the toppings are super quick to prep. And, if you don’t have time for the sweet potato buns, you can always replace them with whole wheat burger buns or ezekial english muffins. To freeze the cauliflower burger... 1. Place the quinoa cauliflower patties on a baking sheet. 2. Put the baking sheet in the freezer for 2 hours. 3. Transfer the patties to Ziploc bags and store in the freezer for up to 2 months. 4. When ready for a delicious burger, place the cauliflower patties in the oven at 375 degrees F until cooked through or in a pan for approximately 10 minutes.
