Pizza - The sun's energy helped make the pizza because the various ingredients required sunlight, either directly, or indirectly. For example, the cheese is made from cow's milk, and the cow's milk comes from a cow who eats grass (presumably), and the grass feeds off of the sun's energy through photosynthesis. Thus, the cheese is indirectly made with sunlight. Also, the grains used to create the flour used to make the dough used sunlight to grow. Finally, the tomato sauce is made from tomatoes, which are a plant that required sunlight to grow.
I only did one example, but I hope you can make another one with the information I provided yourself! Good luck. :)
