I've done the pitas too, they're delicious! I usually spray mine with olive oil on both sides, lightly salt and pepper. Then I lay down a fresh basil leaf topped with halved or quartered grape tomatoes and sprinkle of parmesan mmmm!
This may sound a little gross, but it's actually very good and my son, who's the pickiest eater on earth LOVES it!
All it is, is Mac and cheese prepared like the box directions, pizza sauce (I only use about a half a cup to 3/4 a cup), pepperoni, (Italian sausage or ham work really well too!), canned tomatoes(drained), green peppers and mozerella cheese on top.
Really easy, fast dinner meal, I usually serve it with some garlic bread.
