I don’t know how well anyone follows the frozen pizza game but in 2013 there was an explosion of frozen pizza providers on the shelves because of my old company’s actions. What happened was they acquired one of the largest frozen pizza plants in the US then promptly fired everyone and tried to hire them back at lower pay. For some reason this resulted in extremely high turnover followed even more turnover. By the time they recovered a few years later the clientele was different.
Anyways the pizza I recommend is Costco either frozen or baked. I saw the dough being made and still eat it which is semi-rare.
Also one of the reasons the sodium content is so high is because people love salty bread. Without salt the crust is bland and flavorless. It’s cheaper to add more salt to the dough than increase costs on the sauce ingredients or better meat. To get it down I suggest make your own dough and sausage while using low sodium cheese.
