Roasting browns the surface of food with the high heat of an oven.

• How to roast. Preheat the oven to 425 degrees. Put your food in a bowl. Drizzle it with vegetable oil, and stir until everything is coated. Spread the food out onto a baking sheet so that it's all in one layer with space between each piece. Sprinkle with any herbs and spices you like. Put the baking sheet on the middle rack of the hot oven. Check it after 15 minutes, and stir. Add more time until the food is cooked through, golden brown, and maybe even a little crispy on the edges.
• What to roast. Try vegetables like broccoli, cauliflower, brussels sprouts, potatoes, carrots, asparagus, and butternut squash. Proteins—like chicken, beef, tofu, and tempeh—do well with roasting too.

Steaming cooks food over a pan of boiling water. The food doesn't touch the water. Instead, it's cooked by the steam coming off the hot water. Serve steamed vegetables as is, or add seasonings after cooking. You can't go wrong with chopped fresh herbs, olive oil, or a squeeze of lemon juice for veggies and a dusting of cinnamon for fruits.

• How to steam on the stove. In a pot, add an inch or two of water. Set a steamer basket inside. Make sure the water doesn't touch the steamer basket. Cover the pot with the steamer basket inside, and bring the water to a boil. Add food to the steamer basket. Cover the pot, and cook until your food is fork tender and the veggies are still bright in color. Steaming on the stove top can take 5 to 15 minutes, depending on the size and texture of your food.
• How to steam in the microwave. Put food in a microwave-safe bowl. Add 1 to 3 tablespoons of water, and cover the bowl with a microwave-safe plate. Cook on high starting with 1 minute. Steaming in the microwave can take 1 to 10 minutes, depending on the size and texture of your food and the power of your microwave.
• What to steam. Options include vegetables like potatoes, sweet potatoes, asparagus, beets, broccoli, carrots, and peas. Fish can be steamed until it flakes apart with a fork. Or try it with fruits like apples and pears.

Overcooking changes the color and texture of your food—and not in a good way. Broccoli turns a dull green, and rice can turn to mush. Try these tips to avoid overcooking.

• Set a timer. It can be easy to lose track of time, especially if you're doing more than one thing in the kitchen. Using a timer can help you stay on track. Set it for about 5 minutes before you think your food will be done. You can always check your food and add more time if needed.
• Find a recipe. Recipes can help you understand cooking times for different foods. Find recipes online, or check out a cookbook from the library.

You can also serve many vegetables and fruits raw. You can chop and serve, or bite right in. Try it with carrots, cucumbers, bell peppers, radishes, and turnips. Or try apples, bananas, oranges, mangoes, pears, and strawberries. You can also try changing up your chop. Try slicing carrots and cucumbers into spears, bell peppers into rings, and oranges into half circles.
