Chopped mushrooms, onion & spinach. Mixed that in a bowl with one of those microwavable golden rice packets, plus vegetable oil, salt, garlic powder, & smoked paprika. Stuck it all into the peppers, and into the oven. Didn't bother with pre cooking any of the ingredients or anything (obviously the rice is pre cooked in the pack.)

It came out really tasty. The smoked paprika gave the peppers that barbecued type flavour which I love.
