Ken is back at it in the kitchen and on his new grill!! He can’t just make a plain old burger, oh no! He is always crafting some awesome feast for us in the kitchen and today I bring you this ultimate burger.
Delicious Italian sausage was added to the lean beef, onions were slowly caramelized and mushrooms lovingly sauteed, to all be served on a gorgeous ciabatta bun. We are very lucky folks here!!
Burgers are great all summer long, and there are endless combinations. I was vying for a bison blueberry burger from him but I will take this gorgeous one any day!!

I love caramelized onions! I haven’t had them for a while though because my husband detests onions. Caramelized onions are fabulous on sandwiches… I can only imagine what this burger tastes like… YUM!
Wishing you a lovely day.
