By "awful" you really mean you just don't want to give up meat.
I bet if you took everything I said above into consideration and did the math yourself, I bet you'd find that it wouldn't take much supplementing beans, broccoli, and nuts to meet your workout needs. And if you just give up meat, there's always eggs and milk. Eggs worked for Rocky, after all.
If you're still not convinced, remember that almost all protein supplements are either whey (vegetarian) or plant-based (vegan).
