Preheat oven to 425 and lightly grease a 9x13 casserole pan.
Heat up some vegetable oil in a large cooking pan. Add onions and peppers to the pan and cook until starts to soften.
Add ground sausage, cover and cook, stirring occasionally, until sausage is done. Strain the sausage juice.
In a mixing bowl, combine ricotta cheese, shredded pepper jack cheese, egg, parsley, salt, cayenne and pressed garlic. Mix very well.
Spread a thin layer of marinara sauce over the bottom of the casserole pan. Layer lasagna noodles side by side. (You may have to break one to fit along the side.)
Spread cooked (and strained) sausage with onion and pepper over the noodles. Spread a little more sauce over the top.
Layer more lasagna noodles over the top, side by side. Spread ricotta mixture over the top, evenly. Spread another thin layer of sauce over ricotta mixture. Layer more lasagna noodles over the top and spread another layer of sauce over it.
Spread Italian cheese mix over the top, evenly.
Spray one side of the aluminum foil with cooking spray, the side that will be touching the cheese. This will prevent cheese from sticking to the foil.
Cover the casserole dish with foil and bake for 45 minutes. Take off the foil and bake for another 15 minutes.
