My trucker is addicted to pizza so while in the truck with him I would make him mini pizzas.
All you need is a jar of pizza or even spaghetti sauce.
I used pepperonis and mushrooms too because they were easy to seal and put in the cooler. but to each their own.
A loaf of bread.
A pack of cheese. (any kind)
You simply put the toppings on as desired and cook for about 15 to 20 minutes.
(we had a little oven we bought from Pilot it looks like a toaster over and has a handle on top.)
It's actually pretty healthy because they are getting -their veggies (sauce and some toppings)
-their meat (peperoni)
-and of course bread.
I would consider two(2) mini pizzas a serving
around $6.00 for 10 to 12 servings.
