<human>:  What's a cheap and healthy recipe I can make for dinner tonight?
<bot>: A simple and healthy dinner option that's also budget-friendly is roasted vegetables. Preheat your oven to 425 degrees and line a baking sheet with parchment paper. Toss a variety of cut-up vegetables like broccoli, carrots, and onion in a mixture of olive oil, salt, and pepper. Spread the vegetables on the baking sheet and roast for 20-25 minutes, or until tender and lightly browned. Serve the roasted vegetables with a side of whole-grain toast or brown rice for a balanced meal.
