Leucine-rich protein sources are important such that every meal have ~3-4g of leucine (give or take) so I'd imagine you're likely getting that if you're getting 15-20g of protein from animal derived protein sources.
Coach,
How important is making meat your primary source of protein as a Novice strength trainee?
I'd say half of my protein comes from animal products (milk, cheese, eggs), half of that coming from actual meat. The rest comes from counting protein in other meal ingredients (5g in a banana, 5g per serving oatmeal, beans, protein shake, etc).

Thanks Coach
Ok, thank you Coach
If you truly want to delve into the leucine content of what you are eating to see if you are meeting those amounts, the USDA has a huge data base that breaks down the amino acid profile of a lot of food here
Foods List
You have to select "Full Report (All Nutrients)" near the top to get the amino acid profile broken down fully.
Unfortunately, searching through the database can be difficult, but here is an example of 15% fat ground beef

Yes! primarily, meat is a good source of protein because of the amino acid that it contains. This is one of the basic need of our body.
