There's absolutely no reason to think that you can only absorb 30g of protein per meal. That's a myth made up by supplement companies and backed up by bad science. Check out the link in my signature entitled "Diet Myths Debunked, by Martin Berkhan." You might also want to check out this article by Alan Aragon:
Is there a limit to how much protein the body can use in a single meal? | Wannabebig
The ONLY study that showed some limit to how much protein can be absorbed post-meal was a study that compared the 5-hour response between two servings of lean beef, one serving with 30g of protein and the other with 90g of protein. The study found that the 90g of lean beef protein caused no increase in protein synthesis over the 30g of lean beef protein. Sounds legit, right?
WRONG. The researchers didn't consider the fact that maybe, just maybe, it takes
longer than 5 hours to digest 90g of protein than it does 30g of protein.
Here's the nail in the coffin:
Splanchnic and leg substrate exchange after ingest... [Diabetes. 1999] - PubMed result
After 5 hours the digestion of a pizza was incomplete. Now consider this:
If it takes longer than 5 hours to digest a highly refined food like a pizza, then don't you think that any study that measures the 5-hour response of a whole food like lean beef is deeply flawed? Wouldn't it be more accurate if such studies measured response over longer periods of time, like 8 or 10 or more hours?
The fact of the matter is that your body can digest more than 30g of protein per meal, it just takes a little while longer to digest the extra protein. And a corollary fact is that you do
not need to eat every 2, 3, 4, or even 5 hours. If you have some brown rice mixed with beef and eggs, cottage cheese, and a glass of milk you will have a steady supply of amino acids for at least 8 hours, probably more. So if you choose to consume more than 30g of protein per meal, don't sweat it, your body will still manage to digest and absorb it.
Don't think your body is stupid. For 99% of human history, mankind wasn't able to eat 3-4 times a day, let alone 6-8 times a day. The human body evolved to absorb every last calorie and gram of protein. If it didn't, then our ancestors would've all died out from malnourishment and starvation.
