Ok...... again sorry not a measuring type of cook just a dump and add cook!
Chop onions, mushrooms, green peppers and garlic.
Cook up some Italian sausage (I prefer a mix of hot and sweet)...if you buy it in links you will hvae to remove the casings.
If it is very greasy, drain the grease off, add the onions green peppers and garlic and cook until soft. Add mushrooms toward the end. Dump in some jarred sauce. Add some red wine (a light chianti works nice for this). Cook this down till thicker. Season with salt, pepper, oregano, basil, etc
In a separate bowl, mix ricotta, parmesean, romano, and eggs, season with oregano basil and parsley.
Boil Lasagna noodles.
in your pan spread some of the sauce, place a layer of noodles, cheese mixture, and keep layering till the top. Cover with mozarella and bake
