Tips for toddler that will only eat Plain pasta?

My son won't eat any coloured sauce, but I have for years been making a cauliflower cheese sauce that is the same colour as pasta! Boil a whole cauliflower with 2 x stock cubes for 1/2 hour, add mild grated cheddar and then blend. I then freeze it in ice cube trays and pop it out into bags when frozen. It's quite a mild flavour, and the only way he's eating cauliflower!

Thank you I will definitely try it 😊

I give my 6 year old who I’m fairly sure has ARFID plain pasta, plain chicken and raw cut up vegetables 🤷‍♀️ works
