Kitchen essentials: in the fridge

I'll be out of town next week and I've been thinking about food a lot - what do I consider my essential items? Let's start with the fridge:

• eggs! I am a huge fan of eggs - egg whites in particular. I'm usually starting my mornings with three eggs - either hard-boiled (tossing out the yolks) or scrambled (one complete egg and two extra whites).
• skim milk - I've been drinking skim for well over a decade so I don't taste any difference.
  
• salad - baby spinach always, plus usually some romaine hearts or mixed greens
• Kraft 2% Milk Sharp Cheddar Singles - yes yes, it's processed, but it's 50 calories and melts like a dream. I don't use it often, but when I do, it's oh-so-good
• light sour cream - LOVE it!
  
• non-fat Greek yogurt - Trader Joe's house brand is great, as is Fage. Love the thick texture and I toss in some Fiber One cereal or fruit and it's a great treat.
• English cucumbers - thin skin, but I still get rid of the seeds before using. I make my own tzatziki with the Greek yogurt, garlic, and dill with the diced cucumber. Yum!
• Laughing Cow light wedges - hooray, tasty cheesey substance and low in calories and a decent amount of protein.
  

Next, freezer and then pantry...
