Ingredients
Instructions
- Cook the chopped onions in butter until tender but not brown.
- Spread each fillet with cooked spinach.
- Sprinkle the fillets with the cooked onions.
- Roll up the fillets and place them in a shallow, buttered baking dish.
- Top the rolled fillets with spaghetti sauce.

Tips & Substitutions
For a twist, consider adding herbs like dill or parsley to the filling for extra flavor. You can also substitute the fillets with chicken breast for a different protein. If you prefer a spicier sauce, try adding crushed red pepper flakes to the spaghetti sauce. This dish can also work well with leftover cooked greens instead of fresh spinach.
Serving Suggestions
Serve the stuffed fillets with a side of steamed vegetables or a fresh salad for a light meal. A crusty bread complements the dish well, perfect for soaking up the sauce. For a hearty option, consider pairing with mashed potatoes or rice. This dish pairs beautifully with 'Lynsi'S Favorite' Banana Pudding for dessert.
Storage & Reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place the stuffed fillets in a baking dish, cover with foil to keep moisture in, and bake at 350°F for about 15 minutes or until heated through. Avoid microwaving to retain texture.
