in my ready steady cook bag is sweet potatoes, chestnut mushrooms, onions, mozzarella, natural yogurt

[zippitippitoes]

.....any ideas, I've also got frozen veg and tinned toms and beans

You could probably make some sort of veggie curry, if you discount the mozzarella and beans (assuming these are beans in tomato sauce). Have you got spices/curry powder and rice?

have tinned cannelini, chickpeas,balck eyed beans as well as the heinz ones

yes have curry stuff

Bung a few beans in too then.

If you have eggs you could make a cracking omelette
