This recipe is wonderful!!! I didn't use bell pepper though and I didn't use as much onion as it called for since my husband doesn't care much for onions. I also didn't need to use the 2nd can of chicken broth. I cooked my noodles in water (I thought it was a waste to cook it in chicken broth and then pour it out after) and it turned out great! I mixed the soups, chicken, fresh mushrooms, black olives, and cheese in with the spaghetti, stirred it really well, and then put it in the baking dish. I found that was easier to mix in the pot rather than having it in a dish.
