I got the idea for this pizza from my favorite cookbook that I own:
There is a recipe in the book for a "clt pizza" (cappicola, lettuce, and tomato). I took this as a starting point and modified it. I leave out the lettuce entirely and swap the cappicola out for prosciutto.
In case it isn't obvious, this is called a "Trader Joe's 4-Ingredient Pizza" because it has only 4 ingredients and you get them all at Trader Joe's. I'm sure you could probably do this with ingredients from elsewhere, but this specific set of ingredients forms a perfect suite. They are proportioned such that you don't have to measure or count anything and there are no left-over bits.
The Dough:
This is "Trader Giotto's Pizza Dough". This is a picture of the "Garlic & Herb" variety, but there is also a plain variety that I prefer. This can be found in the same open, refrigerated case as the cheese.
The Cheese:
This picture is a bit blurry I know. It says "Trader Giotto's Marinated Mozzarella in Extra Virgin Olive Oil". It's 10oz. Get the marinated one because you want those spices and whatnot.
The Tomatoes:
This is "Trader Joe's High Lycopene Plum Tomatoes on the Vine". I get the ones on the vine because at some point I read that that keeps the fruit fresher or something. It's labeled 12.5oz.
The Prosciutto:
I normally get a "Trader Giotto's" brand of prosciutto, but this time they were out of it so I got this other brand. You really only need about 4 slices, so prosciutto is the thing you're most likely to have left-overs of, but you can just eat it as a snack.
This recipe is a mixture of the recipe in the cookbook and the instructions on the package for the dough. When it comes to the numbers in this recipe, you're going to have to play it by ear.
This one turned out a bit weird because the prosciutto shrank up a lot:

I have found you can prevent that form happening by kinda pressing is down slightly into the uneven surface of the cheese and tomoatoes before putting it in the oven.
The pizza probably serves 2-3 people depending on how hungry they are. I've made this thing many times now and I have to say, it is pretty foolproof. Like all recipes, it gets better as you do it more times and get more familiar with it. This thing even holds up really well as left-overs.
If you make one let me know how you like it. :)
