You could spray a tin with frylight and put mushrooms , tomatoes and bung in oven for 15 mins , go off and do something ,
have a pan of boiling water ready for a poached egg to do , when the veg has finshed cooking .
if you were on a red day , you could add bacon as well .
i did a really nice roasted veg pasta meal last night , chop up peppers , toms mushrooms , and courgettes with a bit of onion , i added one teaspoon of pesto mixed with the juice of a lemon and add seasoning
roast until nearly done , add a bit of passata , mix and put back in oven ,
start cooking your pasta , and when its done , tip the veg sauce over it .
It was yummy !!
