1. Long beans and beans are crisp, tender and refreshing. After taking them, they give people a delicious feeling of meat, and their nutrients are also extremely high, including protein and carotene, especially the proportion of vitamins and minerals is higher than that of other vegetables and fruits.

Before cooking, enough water can eliminate more than 80% hydrochloric acid in broccoli, and also protect the nutrients of spinach, so that broccoli is full of color and crisp. Therefore, when frying spinach, you must remember to save water. This step cannot be saved.

Broccoli soaked in water is green in color and delicate in taste, and its nutrients will not be destroyed by long-term frying.
