Green Bean Casserole W/ Sweet Peppers & Cheese

Rose Mary Mogan


This recipe came about because I forgot to buy a few items in my original recipe, so I compromised & used the ingredients I had on hand & my husband never knew the difference, he remarked how cheesy & good it was like always.

This recipe is very colorful, & could be eaten without the cheese sauce, once it is combined with the other veggies, but why when it taste so deliciously cheesy good. You can use a less fat milk or even Fat Free yogurt, but not skimping on the main ingredients in the sauce packs a lot of flavor & calories too. It is a once in a while type of indulgence, so enjoy.
