Preheat the oven to 200°C fan / 425°F and lightly grease the muffin tray.
Soak the cashews in hot water for 30 minutes.
Cook the macaroni as per packet instructions.
Meanwhile, add the “cheese” ingredients to a blender and blend together until smooth, then transfer to a mixing bowl with the spinach.
Drain the pasta and transfer the cooked macaroni to the mixing bowl. Mix the pasta with the cheese sauce and the spinach until evenly coated.
Spoon the mac ‘n’ cheese mixture evenly into the muffin moulds. Once each mould is full, press down with the back of a spoon to compact the mixture. Then, sprinkle the breadcrumbs on the top of the bites.
Transfer muffin tray to the oven and bake for 10 - 12 minutes or until the edges are golden brown.
