This is a rich brunch frittata; smoky cheddar and sweet roasted cauliflower make for an indulgence breakfast
Substitute your favourite smoked cheese for the smoked cheddar - smoked gouda would be very nice here. Or use a good, sharp, aged cheddar.
Serve hot or room temperature.
Let frittata rest a least 5 minutes, 10 minutes is even better, before serving. Allowing it to cool slightly helps release the egg from the pan so it will slice cleanly.
