If you're toasting a small amount of nuts, a cup or so, use a pan on the stove over medium-high heat. There's no need to add oil to the pan, as the nuts have enough themselves. Be sure to stir them around frequently so they don't burn. If you plan to toast up a bunch of nuts, spread them evenly on a baking sheet and roast them at 350°F for about 15 to 20 minutes. Use your toasted nuts however you want, like tossed in a salad, or just enjoy them on their own. What nuts do you toast?
