In our daily diet, meat and vegetarian dishes are corresponding, there is meat on the table, there are vegetables, nutritionally balanced meat and vegetables are more healthy to eat, and vegetables generally contain a lot of crude fiber, which can help us speed up the peristalsis of the stomach and intestines and help digestion. Eating more vegetables is not as good for our body. When it comes to vegetables, cabbage, lettuce, and cabbage should be considered very popular, because first of all, there are more leaves, and many people love to eat vegetable leaves, and secondly, it is also relatively cheap, and a whole is only two or three yuan.

Lettuce can not only be cooked but also eaten raw, with a variety of tastes and is loved by many friends.

Lettuce can be made into oyster sauce lettuce, which is light and delicious to eat; It can also be made into a fruit and vegetable salad, which can be made with other fruits and vegetables, squeezed with salad dressing, and tastes sweet and low in calories. So many people have to order a lettuce when they go out to a restaurant, and then they have to order a lot of meat dishes. But we can often find that when you eat at the hot pot restaurant He Sencha, if you order a meatball, you will usually be padded with a piece of lettuce below, and many people are curious, can this lettuce be eaten?

Or is it just an ornament? For friends who love lettuce, if you don't eat it, you feel wasted, but if you eat it, you feel weird, can you eat it?

In fact, this lettuce is at the bottom, and careful friends will find that basically only meat dishes will use lettuce at the bottom, such as duck intestines, beef balls, fat beef, yellow throat, etc. In fact, this lettuce is not small. First of all, we all know that these meats themselves are frozen, after taking them out and cutting them into slices, they will slowly thaw at room temperature, and a lot of blood will flow out after thawing, if there is no lettuce underneath, the blood water will occupy the bottom of the entire plate, making people look like they don't want to eat, but after padding a piece of lettuce, even if there is some blood water, it will flow down the lines of the lettuce, and we basically can't see it.

So this can also increase our appetite.

The combination of lettuce and meat slices, the two colors are matched together, giving people the visual feeling that they are very appetizing, in fact, the meat is still the same meat, but there is an extra lettuce that sets off the Zen skin, and the meat slices feel that the meat slices have become more delicious in comparison. Secondly, lettuce at the bottom has another effect, that is, if a few slices of meat are put in a **, it looks like the amount is relatively small, and customers will think that the merchant is more picky. But if you put a piece of lettuce at the bottom, not only the appearance of the meat slices will be improved, but the main thing is to make the whole dish look bigger, but in fact, there is no difference with the original ingredients, which is also a trick of the merchant.
