Notes
Store: Refrigerate in an airtight container for up to 3 days. Do not freeze as zucchini do not freeze well. If this recipe is too much, cut it in half.
Reheat: Reheat in a skillet with a splash of water while covered. Simmer on low, check and stir every 3 minutes until warmed through.
Ground turkey: Use 1 lb of ground turkey meat for even healthier skillet.
Tomatoes: Regular tomatoes will work too, they just break down more.
Parmesan cheese: It is best to use freshly grated Parmesan and not from a shaker. More flavor and healthier this way.
Onion: Can be replaced with about 1 tbsp of onion powder or flakes.
