I get filled up when I eat a meal with chicken (3 oz.) and a vegetable (1/4 c), then a fruit or carb.
I am still supplementing with a protein shake in order to get in enough protein. I am not eating a full cup at each meal yet (but I'm only in my 4th week). I had a concern earlier with only taking in 465 - 500 calories and had to up that a bit. I haven't had trouble with any foods yet, but have been really, really careful (no bread, etc.), and I chew everything really well.
I have been using a lemon pepper marinade and cooking the chicken in it on the stove top (with a lid) - it's really moist and tender.
Good luck!!
