Easy Variations to Keep It Fresh
Make this your own with seasonal swaps and add-ons.
Swap the protein:
Try turkey breast, salmon, or tofu. For more seasonal flair, you could even go with ground turkey shaped into small patties and roast them alongside the veggies.
Switch the base:
Instead of serving it alone, plate over brown rice, quinoa, or gluten-free pasta. Inspired by my Gluten-Free One Pot Green Chili Chicken Rice, these grains bring fiber and texture.
Go veggie-heavy:
Skip the meat and add mushrooms, chickpeas, or cauliflower. Drizzle with tahini for a plant-powered dinner.
Boost with toppings:
A dollop of Greek-style yogurt, sliced avocado, or chopped almonds can totally change the vibe.
Flavor it differently:
Try spice blends like Cajun, curry, or even Italian seasoning. A tiny bit of grated ginger adds warmth without heat.

FAQs
How many calories are in one serving?
Each serving is about 500 calories, depending on your exact portion sizes and oil used.
Can I use frozen vegetables?
Yes, just let them thaw and dry them with a paper towel first. Too much water will make your dinner soggy instead of roasted.
What’s the best way to reheat?
The oven or stovetop is best to keep the texture. Microwaving is convenient but may soften the veggies more.
Can I double this recipe?
Definitely! Use two pans or roast in batches. Just be sure not to overcrowd the vegetables.
