Start the sausage in one pan that can hold the meat & veggies.
When sausage is half done add onions & peppers. Cook about 5-6 minutes before adding tomato. Start eggs right away on medium heat. When sausage mix is ready keep warm.
Wisk eggs into an extra large skillet or an omelet pan. When the bubbles come through the top, (like pancakes), lay the spich atop one 1/2 and the cheese atop the other. Cook until spinach is warm, (depends on the depth of skillet).
Spread the sausage mixture all over the egg pan. When egg is alost ready to remove, fold one half over the top of the other.
