One-Pot Chicken Arrabbiata

I know this is a super simple meal but arrabbiata is one of my favourite pasta sauces (as someone that doesn't love spice!) and this one-pot version makes it easier than ever, plus cooking everything in one pan makes the sauce extra thick and velvety! You can spice it up or down as you please by changing the amount of chilli flakes or even adding fresh chilli. Give it a save!
