There is something about caramelizing onions that brings out the sweetness and flavor.  This sweetness combined with sausage, gruyere cheese and a bit of thyme make a lovely combination and make a house smell like a home.  This pie is elegant enough for a Sunday brunch with company, but easy and low-key enough for a family weeknight dinner.

Photo of ingredients for low carb sausage, caramelized onion, and gruyere pieSome may be surprised that I have sausage in one of my recipes.  Many people think of pork as an unhealthy meat.  Really, it depends how it is raised.  I use local, organic, pasture-raised pork.  The pasture environment infuses the pork with omega-3 fatty acids making the meat much healthier than the stuff raised in commercial facilities.  Check out your local farmer’s markets for organic pastured meat.

Enjoy!  Simply so savory!
