Another one here for meal planning. I used to be a big fan of the cheapo magazine Super Food Ideas and have heaps of back editions. I randomly pick one and all my meals for the week have to come from that magazine.

We do a big shop once a fortnight where we stock up on pantry staples, meat that we normally use and vegies for that week. In the middle week I'll do another meal plan, but generally we only do a small shop of vegies as there will be enough staples and meat to match that weeks plan.

We only just went back to the meal planning a few weeks ago as we were in a similar situation to you. Shopping all the time, not spending $$ wisely and then chucking stuff out that we didn't use. This way we are eating healthier and spending less $$.
