How to make pickled onions:

Pickled onions add the best flavor to everything, but especially to this burger bowl! Start by chopping up the red onion in half and then into some thin “C” slices. Set aside to make the brine. Take 6oz of water and set to a boil on the stove. Put in 1 tbsp salt with 1 tbsp white sugar into the mason jar with red onion. Pour in the boiled water and then fill the rest of the jar with white vinegar. Place lid on mason jar and give it a spin to let onions soak it up. Store in the fridge for the week!

How to store your leftovers:

I recommend storing your leftover roasted cauliflower in a sealed container in the fridge! I like using these. I’ll also use these Porter Bowls a lot for making pickled onions and storing homemade sauces too!

If you want to switch up these Cauliflower Tostadas, try this:

  • Try using refried pinto beans instead of black beans!
  • Top with fresh red onion
  • Drizzle with a different sauce if you don’t want to make the cashew cilantro sauce!
  • Use this in a taco instead of making it into a tostada.

Can these be prepped ahead of time?

These will be best when making them and enjoying right after! If you have leftovers or want to prep ahead of time, you can roast the cauliflower and make the refried black beans. Pickled onions are also great to prep ahead of time too!

How long does the cashew cilantro sauce last?

You can keep this up to 3-4 days in the fridge! It may thicken up in the fridge and you will want to add a little water to it.

Can I use a different tortilla?

I think corn tortillas work best for tostadas!
