How to Slice an Onion & Crock-pot Caramelized Onions

Now that I am dairy-free and egg-free (I do see myself needing to limit my dairy intake for an extended time, and possibly my lifetime), I am trying to come up with different ways to make the basic salad come alive, since cheese used to be my go-to flavor.  Often times the salad is the last thing I think of in my dinner prep.  I typically serve some main dish with a salad, each comprising of about half of our plates.  I often times don’t even serve myself a true salad, but I’ll just put our organic greens on top of the main dish, like when I have meatballs, pizza (cheese removed for me), enchiladas (again, cheese removed), or really any other main dish, and then I don’t use dressing.

  4. Place one half down on the flat side.
  5. Thinly slice through.

The Verdict: This recipe will make your house smell scrumptious all day!  I had to resist opening my crock-pot and checking on these because the aroma was pulling me toward the slow cooker.

This would be a great addition on veggie burgers or most kinds of meats you may be serving.  It’s also a great addition to vegetables.
