Preservation
The cannery produces the process of preserving food by sealing metal cans airtight to keep food fresh, and sells it in the markets. People shopped not only for food and drinks but also for storage emergencies. A few days ago, I bought some canned tuna and corn in the supermarket. Heating the pan with oil, and frying slices of fresh onions, and mixing with tuna and corn, which I bought in cans. It's an easy homemade dish, and with toast in the morning, breakfast is delicious.
