I wouldn't worry too much about it. From what I understand, kids go through phases of only wanting to eat one or two things. As long as you keep offering the other foods, she will eventually start eating a wider variety again. I would recommend letting her eat the foods she is willing to eat but always offer alternatives with it. As long as she's eating, that's all you can really ask for. Maybe try to put some veggies on the pizza to try to sneak some into her diet. :) If she's too smart for that (which my little guy is), then maybe offer her a daily vitamin while she's going through this phase to ensure she's getting all of the nutrients she needs. Good luck!
