Get My Meal Plans NOW!Supplies needed to make this Chicken Zucchini recipe:
- Large glass mixing bowl: I use this glass bowl for just about everything! It’s big enough to use to make cookie doughs or cake batters in but looks good enough to use as a serving bowl for salads.
- 9×13-inch glass baking dish: I have used this same pan since I received it for my wedding over 10 years ago. It washes up so nicely in the dish washer and I love that it has a lid for easy storage and transport.
- Rubber spatula: These are the best rubber spatulas for cleaning the sides of a bowl. They are heat resistant, stain resistant and can be thrown in the dishwasher to be cleaned.
