not kidding yourself at all, DD1 has been at school almost a year now and has taken pre packaged maybe 3 times.

We usually have a sandwich (i also dont use sandwich bags i use a material lunch pack which i made which is more eco friendly and cheaper!)
Yogurt bought in the big tubs
We do baking every weekend and she picks what she would like for school - sometimes muffins, sometimes cake, muesli slice, scones the possiblities are endless just as long as you check with the school first about any allergies.
Veggie sticks - celery, carrot, cucumber
Cheese and sultanas
In summer we get skewers and different types of melon and other fruits (whatever you like really) and freeze them get one out of the freezer in the morning the kids love them.

I'll have a think more when they arent screaming around me!
