Gratz!
Here's my tip:
Always make sure you have rice and pasta in the house, it's dry and stores for a long time and is sufficient to eat if you're low on other stuff.
Pick up salt, pepper, and a good season-all (like that McCormic one).
If you got a good freezer you should stock it up with frozen meat and veggies (throwing those in a frying pan and pasta on the boil takes No cooking "skill" at all), and if it's a good one, you can buy "large" peices of meat or packets of minced meat, and divide it into smaller plastic bags and put 'em in the freezer, usually comes out to much cheaper per dinner.
Bread, Milk, Cheese, Butter (spread for the bread), cooking oil (suggest rapeseed oil for cooking with, olive oil for using fresh), eggs..
and some jam or something like that, in case you feel like having something sweet
(I would suggest coffee, but you silly canadians don't have that at home *pout*)
