for me its all about mixing in foods that really kick my saliva glands into gear, for me those things would be, peanut butter, avacados, buckwheat with fruit in it etc. I mix my chicken and meats with those and I can get it down pretty easy. For me its all about how I make my meats too, if I make them 2 days in advance and they dry out etc. I cant eat it, but if its fresh like I just cooked it with some fresh steamed rice, 1/2 fresh avocado, little lime juice, salt substitute, and pepper and I can eat that almost every meal and not get tired of it. I eat a lot of buckwheat for carbs since I am gluten free, that with some fruit, or some fresh pico de gallo over my egg whites and I'm golden. Snacks peanut butter and banana, with just a few slices of chicken breast for extra protein most days. I also eat Sardines for snacks for extra omega 3's, way easier to eat for me then any other kind of fast prepared fish.
It is the toughest part eating enough of these bland meals per day. When I hit a grove where I can't eat like that anymore, I dirty it up for about a week, more sauces a little cheating here and there. Then going back on normal meals helps me feel better/cleaner less bloat etc. so I have a much easier time for a few more months.
