We like this as a vegetarian main dish or as a side for a meat main. You can also double it and use a larger pan to feed a crowd. Updated in Sept 2020 to use instant brown rice to ensure the rice cooks through.
Preheat the oven to 375 degrees F. Add the rice and chicken stock to a 2 or 3 quart baking dish. Cover with foil tightly and bake for 30 minutes.
Remove from oven. (There may be a little liquid in the pan and there may be a few bits of rice that aren't yet 100% super soft yet. It's okay as it will keep cooking in Step 3!)
Stir in the peas, zucchini, Parmesan, butter, and salt until well combined. Cover with the foil and bake for 5-10 minutes or until the peas are warmed through and the zucchini is just soft.
Serve warm.
Notes
Store any leftovers in an airtight container in the fridge for up to 3 days. Warm to serve.
Vegetarian: Use vegetable stock to make the dish vegetarian.
Stir in 1 teaspoon fresh thyme leaves before serving for more flavor.
