Vegan Grilled Cheese with Caramelized Onions

When I went vegan, I thought grilled cheese was out of my reach. Of course I could use one of the commercially made vegan cheeses on the market, but I don’t think their ingredients are ideal.  So I was left to create a vegan grilled cheese from whole food ingredients.  We have been using our dairy free cheese sauce in many recipes lately, so I thought I would test it out by making this vegan grilled cheese.  It’s not only good, but the caramelized onions boost it into awesomeness.

The only downside to this vegan grilled cheese is that they need to be made to order.  However, the onions and the cheese sauce can be made ahead of time.  You will just need to assemble the sandwich right before you choose to eat it.  These vegan grilled cheese sandwiches were so good, I am already thinking of all the variations I could come up with.

    1. In a saucepan, on medium low heat, saute the onions in oil and salt. Cover and continue to saute until the onions break down.

    1. I'm not a huge fan of sandwiches in general, but this sounds incredible. I may just need to pull that sourdough buckwheat bread out of my freezer for this! ;)
    2. Is it possible for you to recommend a natural whole foods supplement (a BRAND). I am new to clean eating and have been taking One-A-Day supplements and starting to think this was not a good choice. Thanks Michele
    3. I was so happy when I clicked on this to see that it wasn't processed vegan cheese (which I'll eat but just don't love!) I'm always at a loss for vegan sandwiches and can't wait to make this one !
    4. Melissa, I made this tonight and it was AMAZING! I really didn't think anyone would be a fan of the cashew cheese sauce but it was a total hit :D Some of us prefer Miracle Whip while others prefer regular mayo, so I did use them (I've given up a lot of processed stuff but M.W. and mayo ain't one of them) but I think it just added to the awesomeness. I had some tomato soup ready for dipping...soooo goooood!! Definitely making them again, thank you!
    5. Made this tonight. Fabulous!! I used veggie broth instead of oil to saute the onions. Can use a nonstick skillet to grill the sandwich in order to avoid the oil :) Will definitely make again!!
