Hign protein food plans

Options
Morning all, currently going down the high protein, minimum excercise route - circa 20km cycles - 2 to 3 times a week.
So far working well - not to pushed re a variety of meals - happy to eat same over and over as long as the results happen.

Anyone else trying this? run into any issues/, have any pointers as to what food stuffs work best?

Cheers,
Owen.
