Final answer:
To cook bread in a fuel-efficient way, you can use a convection oven or a toaster oven/microwave.
Step-by-step explanation:
If you want to cook bread in a fuel-efficient way, one option is to use a convection oven. Convection ovens have a fan inside that circulates hot air, resulting in faster and more even cooking. This can help reduce cooking time and energy consumption compared to traditional ovens. Additionally, using a toaster oven or microwave to cook small portions of bread can also be a fuel-efficient option, as they heat up quickly and use less energy overall.
