This Cheesy Stuffed Bell Pepper Casserole is one of those recipes that quickly become favourites. My family and I were debating what to have for supper last weekend. We wanted something that felt like homemade comfort meal without requiring us to spend hours in the kitchen, while still being full of vegetables and protein.
An “unstuffed pepper casserole” is a simple midweek supper that a close friend of mine has been sharing with me. She was adamant that it was one of those dishes that goes out of style before anyone has had a chance to try it. I finally made the decision to try it, and now I totally understand why she continued to suggest it..
