# Tips for Success:

01 -
  • It captures everything you want about pizza, the cheese, the Italian flavors, the pepperoni without any of the carb regret
  • The whole thing comes together in 40 minutes flat, and most of that time is just the oven doing its job
  • You can prep it on Sunday and have lunch sorted for half the week
02 -
  • Drain any excess liquid from your vegetables after sautéing them, or you'll end up with a watery casserole
  • Letting it rest for those 5 minutes makes the difference between a slice that holds together and one that falls apart immediately
  • The cheese continues to melt and set after you pull it from the oven, so don't judge the final look too early
03 -
  • Grate your own cheese from blocks instead of buying pre-shredded, it melts so much better
  • Line your baking dish with parchment paper for next-level easy cleanup
