Preheat your oven to 400°F (200°C) or your air fryer to 375°F (190°C). Wash and chop the mixed vegetables into uniform pieces for even cooking.

In a large bowl, toss the chopped vegetables with olive oil, salt, pepper, garlic powder, and paprika until evenly coated.

For roasting, spread the seasoned vegetables on a baking sheet and roast for 25-30 minutes, stirring halfway through until tender and caramelized. For air frying, cook for 10-15 minutes, shaking halfway through.

For sautéing, heat a tablespoon of olive oil in a skillet over medium-high heat. Add the seasoned vegetables and sauté for 5-10 minutes until crisp-tender.

After cooking, remove from heat and optionally drizzle with balsamic vinegar or sprinkle slivered almonds. Serve immediately.
