I only recently discovered caramelized onions and discovered this technique by mistake when I was grilling chicken and some vegetables one day on my counter top George Foreman. I realized the onions started to look and smell just like caramelized onions made on the stove top. I have started making my onions this way since then. I love to use it in sandwiches. I usually make one serving for myself, which is how I wrote the recipe. Just up the amount of servings if you wish.
