Preheat oven to 200°c. Line a baking tray with baking paper. Mix breadcrumbs and milk in a large mixing bowl and set aside for 5 minutes
Heat butter and oil in a frying pan. When the butter stops sizzling, add the diced shallot and garlic. Cook over medium heat for a minute or two until soft and fragrant. Stir in the garlic powder and cayenne pepper. Remove from heat.
Add the chicken mince, parsley, sage, and salt to the bowl of soaked bread. Add the cooked shallot and garlic mixture, and wipe out the frying pan. Mix the meatball ingredients with your hands until well combined, and shape into golfball-size balls.
Pour a thin layer of olive oil into the frying pan and heat to medium-high. Sear the meatballs in batches, about 9 at a time, placing them on the paper-lined oven tray as you go. Don't overcrowd the pan, or else the meatballs will stew and won't brown.
When all the meatballs are golden brown, bake them in the preheated oven for 10 minutes. Cut one ball in half to check that they are cooked through the thickest part of the patty. If they are still pink in the centre, return them to the oven for a few more minutes.
Meanwhile, Make the Orzo/Risoni
Wipe out the pan again, and heat butter over a medium heat. Fry the sage leaves until they begin to crisp, then remove with tongs or a slotted spoon to a paper towel.
Add the shallots and garlic to the butter in the pan and cook for a minute or two until they are soft and fragrant. Stir in the orzo/risoni ensuring it is well coated in the butter and shallot mixture. Turn up the heat to medium high and add the wine and thyme. Reduce heat and simmer for 3 minutes. Add the chicken stock, bring to a simmer and cook for a further 7 to 10 minutes. Stir frequently and keep testing the orzo/risoni for doneness, as different brands have different cooking times.
Add the cream and spinach and simmer, stirring, until spinach is just wilted. Stir in the parmesan.
To serve, spoon the orzo into bowls and top with the meatballs. Sprinkle over the extra chopped parsley and grated parmesan, and top with crispy sage leaves.
