Melt the 20g of butter in a pot, then add in the onions. Cook on low heat until the onions have caramelised and the butter has browned.
Add in the pastina, miso & pepper. Give it a mix before kissing it with the white wine. Cook off for 1-2 min before adding in the chicken stock.
Stir continuously, so it doesn't stick to the bottom. Add in a handful of grated Parmesan. Mix again. Repeat.
Serve with a drizzle of olive oil, chilli oil, more Parmesan & chives
