Do you know about Naan pizza? Pronounced "Non" not "Nan." It's probably the easiest dinner/lunch/snack. It's delicious and fully customizable. Naan is Indian style (India the country) Tandoori flat bread (Tandoor is the type of oven its cooked in).
You can probably find it at your grocery store, sold in packs of two like this. I really like Wegmans garlic Naan. This also happens to be a favorite design that I worked on. I got to give it an Indian feel, which was really fun. India will always have a special place in my heart because of the two trips that I took to this amazing land. More on that another time.
Place the Naan on a baking sheet. If you would like to make clean up even easier, use NON-STICK foil. Regular foil will be more trouble than it's worth.
Add whatever toppings you like. Sauce, cheese, vegetables, artichoke hearts (my favorite), spinach, pepperoni, basil, fresh herbs - you can literally clean out your fridge AND make a delicious pizza. See recipes here.
I will say this, the more toppings you use, the longer it may need to bake in the oven (or on the grill).
This is a gluten-free pizza dough that we also used. It came as a dry mix in a bag. We added the wet ingredients, spread it in a pan and pre-baked it before adding toppings and finishing it in the oven.
Into a 325-350 degree oven for 15-20 minutes (or more) depending on how crispy you like the crust.
Pizza is always a hit and everyone can participate by making their own. We made them a couple weeks ago when our family was visiting. Easy as pizza pie!
