Not bad. The directions instruct you to bake 45 min 'or until cheese is melted' but if you bake just until cheese is melted, your frozen green beans are sure to have not even warmed through yet. I figured I could build dimension to the flavors instead of just mixing the ingredients and baking them. I ended up sauteing onion, sliced baby bellas, and garlic in a pan, then added the beans and deglazed with a little white wine. Let it cook down to almost dry and added the cooked sausage and sauce. I baked it 20 minutes or so with the cheese on top and served over mashed potatoes. It was good and filling, good for a weeknight dinner, just not a wow dish. I don't use a lot of jarred sauce so perhaps I didn't pick one pleasing enough to the palette.

This was really good. I didn't have any mushrooms so I used an onion. Also cooked up some garden green beans and used them instead of frozen. It makes a lot and would be good to bring to a pot luck.
