Almost all my "skinny" food have already been listed, but one I didn't see above are Alternative Bagels and pitas. They're a little hard to find, but they finally started selling them at my grocery store. They're high in protein and fiber and a little lower in calories and carbs. I top them with whatever I have around... tuna, turkey, or natural peanut butter are a few options.

some great answers which I will be transferring to my shopping list! :) :)

I forgot:
canned tuna
low-cal hot choc
salmon, sweet potato mash with carrots and brocolli makes a great & healthy (&easy) dinner

A new just discovered food
 

I went to the store for some crackers to have with my beautiful salad for lunch, the Special K Crisps were on sale, so I tried them, 110 calories for 30 of them, and 10 was plenty to accompany my salad. They taste somewhat fake (like rice cakes?), but fill a potato chip desire!

Other go to foods - Mashed Cauliflower.
Dr. Praegers Spinach pancakes,
Cottage cheese with hot salsa (an acquired taste!)

If you can find them, Flatout Crisps are great...high fiber, whole grain, protein, and good fat; a healthier nutrition profile than most of the crackers out there.

oat bran
dried coconut, no added sugar
cacao nibs
tons of fruit (i love them all)
tons of veggies (eggplant, leafy greens, and red peppers are my fav)
olive oil
lemon
dry rubs
chicken thighs, no skin
whole grain bread
veggie and bean homemade soups
cheese (in moderation) it keeps me full
canned pumpkin
all nuts
olives
pickels
all natural peanut butter with cayenne pepper on top of beans, served hot! :)
any kind of plain yogurt (greek or not)--i stay away from the fruit flavored ones bc they have too much sugar in them. instead just add your own fruit. also, i think the ones with fat in them are healthier for me bc they keep me satisfied.
1% low fat milk or almond milk
tea
lots of water

apples
eggs
almonds
I love spinach salads!

These are the things on my diet I never get tired of:
Bacon
Coffee with heavy cream
Oven roasted cauliflower - yummm
Green bean crisps
Artichokes
Palm hearts

I read somewhere that human beings were meant to only eat vegetables based on the type of teeth we have.

Also, communities whose citizens live longest only eat meat once a week, according to one Time Magazine article. Just a thought ;)

soft boiled eggs on whole wheat toast
lentils
spinach (cooked, in salads, everywhere)
broccoli w garlic & lemon
bananas (love after workouts, or before runs if I've not eaten, or @ night if I've got the munchies)
ham
tuna w/ green onions & celery
greek yogurt
tilapia
shrimps (w garlic, paprika, lemon & olive oil)
turkish coffee
frozen berries
whole grain mustard
broth

I love tomatoes, but can't find any nice ones. Thinking of growing some instead, but it seems complicated...

Oven roasted Brussels sprouts, and any other vegetable roasted for that matter.

Lentils (eaten with the vegetables).
