SOS! Someone Please Organize This Cupboard!

I have a lovely, nice-sized kitchen. One thing it's missing, however, is a designated pantry. So here is my "pantry," a large lower cupboard with a funky weird shelf. In it (as you can see) I keep pretty much everything food-wise except for baking supplies and cereal boxes. (Sorry for the poor quality pics, my flash wasn't working). There's not much I like about this set-up; however, I'm sure someone with better spacial reasoning skills and an eye for organizing would be able to make this much more usable. I resisted the urge to straighten this up to take the pictures, because I want you to see what I'm actually dealing with on a day-to-day basis. 

 

 Does looking at this give you hives? I try not to focus too much on it because it gives me anxiety. So I need YOUR help and ideas to get this cabinet organized and usable for $30 or less (preferably less). I've been on Pinterest and I've browsed the home/kitchen organizing things on Amazon and in stores and haven't found anything that I think will really work for me. Here are some of my thoughts.

• I have looked into and discarded the idea of those pull-out shelf things. This is a very deep cabinet and I haven't seen anything that would actually work that would fit in my budget. It works for me to keep the canned goods on the narrow shelf at the top, but I'm wondering if there's a better way to store them or if I'm using this shelf to its best advantage.
• Other challenges I have are named Brady, Reid, and Audrey. They get in here and make a royal mess. I keep this latched close for the toddler's sake, but the older ones can get in. Which brings me to another challenge.
• I need to get in and out of this cupboard quickly, due to the aforementioned toddler trying to climb through my legs to get to the chips. So I don't always have time to keep things in an orderly fashion. Whatever I do end up with needs to make it EASY to keep it organized.
• I COULD eliminate the narrow shelf if I found some awesome solution that would necessitate its elimination. 
• I feel like there's a lot of "wasted space" here. See how things on the bottom get shoved under that shelf? aka the "Black Hole"? 

So how would YOU organize this cupboard? I'm hoping all you right-brain, organized, neat-freak people out there will send me your best ideas! 

I'm trying to tackle my kitchen this February, so this will be the first of several posts where I ask for you help and ideas to make the "heart of my home" a little less stressful and a lot more user-friendly.

(yes, we go through a lot of applesauce)
