Turn your oven on to its highest setting. Don't worry the meatballs won't be in there long enough to burn.

Place meatballs in a roasting tray. Halve cooked beets or quarter if large and pop in the tray. Transfer the tray to the oven (don't wait for it to come up to temperature). Set your timer for 13 minutes.

When the timer goes, check the meatballs. If they're not ready give them longer in the oven. When they are browned and cooked through (no longer pink inside), remove from the oven and scatter over the cheese so it melts from the residual heat.

Serve tray in the middle of the table with baby spinach, pickles and ketchup or mayo (or both). Let everyone create their own bowls.
