Definitely what I keep (keeping in mind that I'm 23 years old and HATE cooking and don't have oodles of time)

-Cans of broth (also bouillion cubes for flavouring)
-cans of tuna, salmon and other fish. Cheap and nutritious!
-Pasta (I love pasta)
-Garlic salt (love garlic and salt)
-Salt/Pepper
-White sugar, brown sugar
-Flour and baking powder
-Cans of soup
-Crackers
-Onion soup mix (good for use in recipes)
-Cans of vegetables and beans (you never know when you'll need them)
-Cans of tomato sauce and tomato paste (good to be used in lots of stuff)
-Chocolate chips AND other baking chocolate (yum)
- Vanilla extract (used in a lot of baking)
-Macaroni and cheese ("KD") boxes
-Instant noodles
-Rice
-Hamburger Helper mixes, "side kicks" (instant side dishes, like potato mixes, instant rice mixes, and instant noodle mixes)
-Jello mixes
-Pudding (mixes or pudding cups, yum)
-flavoured juice crystals or water crystals (add to water = flavoured water, add to water can also make juice, like Kool Aid!)
-Peanut butter and honey
-Cereal (I don't like oatmeal, but you can also get that)
-Oils (cooking oils) olive oil or sunflower oil is a good thing to have
-Vinegar (white vinegar can be used for cleaning things too... but apple cider vinegar and others have different flavours)
- Trail mix, granola bars or cereal bars - something that has some protein in it, that's also easy to eat on the go!
- Tea bags and/or coffee filters and/or ground coffee and/or powdered milk or "coffee whitener"

In the fridge:
-Cheese! (I love cheese. If you do multiple things with cheese, get a block of cheese, possibly cheez whiz, and processed cheese slices)
-Ketchup, mustard, relish
-Pickles (and/or other pickled vegetables you like)
-Eggs
-Bread/bagels
-Milk
-lard or equivalent
-butter or margarine
-Soy(a) sauce
-Hot sauce (I got "Louisiana Hot Sauce" which isn't horribly spicy, but adds a nice kick to food)
-jam/jellies
-salad dressings
- whipped dressing/mayonnaise
-carrots/apples/other staple veggies/fruits you enjoy
-sour cream, yogurt, cream cheese, etc

Other assorted veggies:
- Onions
- Garlic
- Potatoes
all have a long shelf life, but should NOT be refrigerated!

For the freezer:
- Frozen hamburger/chicken/other meat/bacon
- frozen fish fillets and french fries
- frozen veggies (you can get cheap mixes)
- frozen waffles or something like Pop-Tarts if you like those
- ICE CREAM (Yes, it's important ) - I suppose for a healthy alternative, frozen yogurt?
- frozen fruits (usually berries) -> good for smoothies and baking!
- Ice packs (very important to have freezing in case you need one!)
