Hah. I know the feeling. I have this great little felt bag that I got at the Container Store about a year ago and it's become my lunch bag. I looked in it just now to see what I have:
homemade yogurt w/ organic wild blueberries (already eaten)
fresh tuna that I grilled last night and made into tuna salad
packet of almonds
carrots and cucumbers (for dipping in the hummus)
Funny how my likes wants have changed!
