Just some ideas(and maybe save you a little time reading labels)some of the things I buy are....
skim milk (I grew up always drinking 2% cause that's what my sister had to have but just slowly cut back to skim and now reg milk grosses me out...and whole milk now-forget it)
I buy Scwhebels light bread(white and wheat)are 35 calories...and that's for "2" slices :happy dance:
for butter I like the blue bonnet light.
I always do fat free sour cream....alone(like as a dip)I think the flavor may be just slightly off of reg...but not enough to dislike it and on tacos and stuff I can't tell the difference at all.
I also like the red fat cream cheese.
no difference for me either w/the new 2% velveeta.
kraft also now has the bags of fat free shredded cheese which I like.
although I haven't bought ALL the baked chips...I do buy the tosito baked scoop tortilla chips and love em.....only taste diff for me is I think they taste FRESHER

(although they are pricier than reg)
fat free cool whip is also deliscious!!!
I also like alot of the light salad dressings but I find my favorites are always the asian ones-(I have yet to try an asian light dressing that taste any diff from the regular)I also like the good season sun dried tomato dressing...
I'm sure theres tons of others but those are a few of my staples.
