Saturday afternoons at our house are always a swirl of grocery bags, muddy cleats, and hungry tummies. One weekend, after a long morning chasing the kids through the park and my husband helping our neighbor fix a flat tire, I stared into an empty fridge, except for a container of leftover chicken and cooked rice from the night before. My daughter walked in, cheeks pink from play, and said she was “starving but not in the mood for cereal.” Perfect challenge.
I grabbed the chicken, rice, steamed broccoli, and some peppers I’d forgotten about. Tossing it all with teriyaki sauce felt fresh and lively, and once I added the soy, garlic powder, and onion powder, it smelled like dinner I’d actually want to eat.
An hour later, I pulled a bubbling casserole from the oven, cheesy on top, saucy underneath, with the veggies soft but not mushy. My son dove in first and declared, “This is a keeper.” My husband took a second helping before the game even started.
That moment when family gathered around a simple dish that tasted like more than the sum of its parts, was exactly why I cook. No fancy gadgets, no mystery ingredients, just practical, comforting food made real.

Cooking Instructions
Step 1: Preheat & Prep
Preheat oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with olive oil.
Step 2: Mix the Filling
In a large bowl, combine chicken, rice, carrots, bell peppers, broccoli, and peas.
Step 3: Season & Coat

Step 4: Assemble the Casserole
Spread the mixture evenly into the prepared baking dish. Top with shredded mozzarella cheese.
Step 5: Bake Covered
Cover the dish with foil and bake for 25–30 minutes until veggies are tender and cheese is melted and bubbly.
Step 6: Crisp the Top
