Combine all ingredients in a small pot and stir well. Heat over medium heat until just starting to bubble. Remove from heat and add to the lasagna.
In a large skillet over medium heat, add ground beef and break up beef stirring occasionally until no longer pink. Push beef to the side of the skillet. Remove excess fat (if any) with a few paper towels.
Add the onions and cook 2 minutes. Add the frozen peppers and cook 6-7 minutes until most of the water has cooked out of the pan. Stir together with the beef, garlic powder, onion powder, dried oregano, salt and add cauliflower rice.
Add the pizza sauce and stir.
Turn on broiler
Add optional grated cheese to the top and broil 1-2 minutes (if you are using a stainless steel pan with a stainless handle). If you aren’t using a stainless pan you can just add the lid and allow to melt, no broiler needed.
