"This recipe is way, WAY BETTER than the cream soup version," according to Baseballmom_88. "The fam LOVED it! I made this with fresh green beans (cooked earlier)."

"The sour cream sauce is great with the cheesy layer on top," raves Melanie. "I added chopped mushrooms into the skillet with the onion mixture."

"It was delicious, easy to prepare, and I definitely will make it again," says Stellazine. "Only thing I changed was the topping — I sprinkled bacon bits instead of the cracker crumbs. It's a keeper."
