If you have an electric or gas grill, nothing could be more simple. Simply turn the button (for the gas model, make sure the gas tank is securely attached) to your desired heat setting.
If you have a charcoal grill, use a grill lighter or a fire-starting gel, which will light it quickly and easily. Alternatively, you can go totally old school and start the fire using wooden sticks and newspaper. Once you've lit the newspaper on fire and the wood starts burning, add coals little by little so you don't put out the flames.
