Four of these run less than $4 at Aldi.
Coupled with a tortilla or flatbread, one of them makes a nice utensil-free main course at lunch. You can dump the chicken salad straight onto the tortilla and then use the edge of the tortilla to scoop out any that doesn’t dump.
I would say my goal is to eat a healthy, balanced lunch, but really right now it’s just to shove enough food in my face so I don’t eat everything that holds still long enough when I get home (I’m not currently feeling epic salads, for some reason).
So there you go. These and a pack of Aldi’s flatbreads gets you a decent main course for less than $2/lunch. Add Greek yogurt (low sugar for me; too much and I’ll be cranky an hour later) and maybe some store-brand Grape Nuts and you’ve got a decent, inexpensive meal to get you through the afternoon.
