The profit of selling vegetables depends on many factors, such as variety, quality, selling price, purchase cost, transportation cost, loss and so on.

The profit rate of selling vegetables is not high, and the average gross profit margin is between 10%-20%. The price of each dish is 1 yuan/kg, the cost is 0.8 yuan/kg, and the profit rate is (1-0.8)/ 1=20%. If you sell vegetables for 1000 yuan a day, the profit is 1000*20%=200 yuan.

The actual situation is not simple. You need to pay some extra expenses, such as transportation, packaging and rent. Dishes will be damaged during transportation and storage.
