My method of cooking is generally like one long episode of Ready Steady Cook- I tend to shop randomly around special offers, and then every day I make up our meals based on what I have in the cupboards/fridge. Today I had a picnic lunch planned with some friends and the kids- I wanted to make a quiche to bring, but when I checked up on my supplies I realised I only had 1 sweet potato left (this is my usual quiche crust, click here to see), and I had completely run out of cheese, other than mozzarella and parmesan!

I’ve had a go at a sweet potato and oat pizza base before, which tasted lovely but was way too sticky to the tray, so I thought I’d try this for the quiche base, and it worked an absolute treat! It crisped up nicely in the oven, and made a solid and tasty crust for the quiche, definitely an excellent, and healthy, alternative to pastry. I used mozzarella in this as it was all that I had, but really any cheese would do. I filled with bacon and topped with asparagus but you can use any fillings that you have in, here are some more ideas!
