Are you switching up your meats and trying different combinations of seasonings. I really REALLY plan on keeping it switched it up so I don't get bored. But even then I can get tired of chicken..usually I'll just look for a different different recipe. Lately I've been trying different fish, I'm going to have pickerel tonight and basa this weekend and probably salmon later on during the week. So I know I have the fish covered this week but last week I ate mostly chicken.
Quite honestly I never had eggs for a meal until the last month or so and right now it's because it's 'quick' more so then 'lean'. I've been spinning in my life and I found if I plan a few meals ahead of time and keep the different types of meat I don't get 'tired'. But at least recognizing your tired of it will help you find different ideas!
