Slice the green onions into thin rings. Dice the zucchini, carrots, and red bell pepper into small, bite-sized pieces - aim for about ¼-inch cubes so they cook quickly and distribute well in the muffins.

Heat 1-2 tablespoons of the oil in a large skillet over medium heat. Add all the chopped vegetables and cook for 7-8 minutes, stirring occasionally, until they're softened but still have a slight bite. Season with salt and pepper. Remove from heat and allow to cool slightly.

In a large bowl, whisk together the buttermilk, remaining oil, egg, dried rosemary, and chopped chives. Season with salt, pepper, and a pinch of freshly grated nutmeg. Stir in the flour and baking powder until just combined - don't overmix. Gently fold in the sautéed vegetables until evenly distributed.

Preheat oven to 350°F (180°C), or 320°F (160°C) with fan. Line a 12-cup muffin tin with paper liners or lightly grease. Divide the batter evenly among the cups. Bake for 25-30 minutes, until the tops are golden and a toothpick inserted into the center comes out clean.
