I find if I put the fruits and veggies in the veggie bin, I forget they are there and they just rot without being used. Try moving them to the top shelf so you can see them. I also buy a lot of frozen veggies rather than fresh, they taste just as good and they just stay frozen until I'm ready to eat them. I get bags of the store brand mixed frozen veggies, I think I pay $1 a bag on sale and I get 4 servings out of each bag. Less prep work, too. I just dump what I need in a small serving dish and nuke until hot. No cleaning, cutting, scrapeing or peeling needed!
Also, try to buy smaller quantities of fresh food when possible, no use in stocking up if it all goes bad before you can eat it!
When I make a big batch of something, I just freeze half of it right away. With what's left, I usually have enough left over for one meal, which usually gets eaten the next day. Then next time instead of having to cook again I can just talk out the part I froze and defrost it. Great for nights when I don't have time or just don't feel like cooking.
