In regards to eating meat

[Monica]

Well, 10 eggs compared to 50dkg meat was my base because 10 eggs is basically 2 meal for 2 if we do nothing else.
The meat is the same (with rice, but that is like 0.15$ per serving if we boil it down to that), 50dkg lasts for us for 2 meals with added rice. But eggs alone are rather plain, so one needs...something to go along with it. Cheese? I do not even know . D

Here is the US people usually eat eggs with some sort of bread and/or potatoes. Cheese can be added too if desired, but 2 eggs provides a good amount of protein.

But the beans is a good suggestion. Definitely going to check the prices of that tomorrow.

Great! We usually have rice with beans. Together, they make a complete protein.

Any grain + any legume (beans, peas, lentils, etc.) = complete protein. Milk is also a complete protein, as are soy and quinoa. Lowfat cheese might be, but higher fat cheese isn't a very good source of protein, as it's mostly fat.

You don't have to really think about it too much, because they tend to go together anyway.

Peanut butter + bread
Rice + Beans
Corn or wheat + beans
