finallyready

Hi,
I'm finally ready to start doing something about the weight that I have gained over the last 3 years. I'm starting an exercise routine today..or at least I'll exercise today I'm still trying to map out a rountine but need help with my diet. I'm a big snacker which is my problem I don't like sitting down to huge meals i like to pick away but that probably leads me to over eating or eating bad things. An example is my favourite thing is salsa and chips so I make home made salsa which is all fresh tomatoes, cilantro, pepers all good for you and I crisp up some whole wheat pita bread torn all apart so it's thin like chips. I love it and would be happy eating that all the time or leaving the pita hole and piling it with all different veggies and a little bit of tomato sause as a mini pizza (no cheese even) but i probably end up eating two -three pita's at 130cal each and it's all carbs right?? Anyway I'm 29, 5'5 129lbs female and was wondering how this is for a plan for food I was thinking for breakfast a couple of eggwhites, for lunch veggie salad with itatlian dressing for a snack when i get home some cut up peppers or other veggies and for dinner either salmon, chicken or lean ground turkey with lots of veggies/salad and occasionally some brown rice. (I don't like fruit so that can't be a snack and I don't like tuna so I can't put that on the salad at lunch) Right now I eat soup or salad for lunch and then do lots of snacking through out the evening usally not really having a dinner just cheese & crackers, maybe a lean cusine or a handful of pretzles...just stuff here and there. So when I think of sitting down to a "meal" I worry about gaining even more weight because an hour later I"ll want to snack so I guess I skip the meal and just snack cause I know I"ll do it anyway?? Any advise
