I make a homemade pizza nearly once a week. I wouldn't touch what you just described.
1) The crust would be a maybe, prepackaged stuff isn't too bad. But if you really wanted to go all out, make your own crust.
2) The sauce is a definate no. Spaghetti sauce isn't pizza sauce. You need spices and flavorings in the sauce or it will taste bland. If you can't put things in it (chopped garlic and onion are a must) because of your GF, try hiding stuff in the sauce (garlic powder, cayenne pepper, ground pepper, etc). Also, if the sauce tastes strongly of tomatoes, you need to add salt.
3) Your topping was lacking. I hope at least it wasn't that preshredded stuff. If you think it is boring, why didn't you add flavor there? It takes less than five mintues from start to end to roast some peppers, grape tomatoes, onions, etc. If you really want to go all out, you can roast garlic in maybe 15 mintues (it takes more time to peel and cut it). Then just toss them on. But then, I find maranara pizza to be quite boring.
