You can reheat your roasted frozen vegetables, but I find they're best eaten within 1-2 days of roasting.
This base recipe gives you so much freedom to add your favorite seasonings and flavors. I love mixing in garlic powder, Everything But the Bagel Seasoning, Montreal Steak Seasoning, and grated Parmesan.
