When switching to a Paleo diet, breakfast is the hardest aspect of the transition. All those traditional breakfast foods -- cereal, bagels, toast, pancakes, waffles, Danish -- are off limits. Sure you can buy special (expensive) flour and try to make these products yourself, but why not eat simply meat and vegetables?
Here's what I had for breakfast about an hour ago -- sausage and zucchini.
The sausage is store-bought, Applegate Farms Chicken & Sage (although I also make my own occasionally). I fried the zucchini in ghee with red pepper flakes to give it some flavor.
A breakfast like this keeps me satisfied for six hours.
