All you need are pitta bread (alhamdulillah pitta's are great to store in the freezer ready on standby!), tomato puree, and any melting cheese.
I usually lightly toast the pittas in the toaster before just spreading a very small amount of puree, finish with cheese and any other topping that might be in the fridge!
Put under the grill to melt then cut into quarters and serve on a big sharing plate!
Lunch in 5 minutes....done!
