2 large red onions (you can use yellow if you prefer)
1 (3-4 pound) chuck roast
2 teaspoons Celtic sea salt
3/4 teaspoon freshly ground cracked pepper
4 large potatoes, cut into bite-size pieces (the modern Paleo diet allows for white potatoes on occasion, but if you prefer to avoid them, you can substitute with sweet potatoes or other root vegetable such as parsnip)
8 carrots, cut into 1/2″ coins
