Most of you have included PB and eggs (and we already assumed we'd have sugar) so with 1 cup PB, 1 egg, and 1 cup sugar - you can make awesome PB cookies - my kids love them. Throw in a few choc chips if you have them in the cabinet and you have PB/chocolate chip cookies - yum! I might have to make those tonight now!
I fall into the apparently more rare category of "the next pay day" could literally be 30 days away if it's a 31-day month...so obviously, we couldn't do that on $25! Again, we also have dietary considerations so that makes it more difficult (dd - no soy milk; ds - no milk/products!)
Items I'd buy:
gallon skim milk ($1.98 - was on sale at Kroger for 1.98 this week)
2 qts soy milk (5.00)
2 boxes pasta (1.66)
4 cans pasta sauce (3.52) (the cheapest in the cans is cheaper than buying the tomatoes to make it)
2 pks Italian sausage (3.99 BOGO this week))(or any other bratwurst, sausage, on sale) - cut up and put in with pasta/sauce....use pieces sparingly
2 doz eggs - (1.98)
ww bread (1.76)
PB (2.00)
jelly (2.00)
3 bags carrots (on sale at Kroger for .39/bag)
Total is $25.06
Also, I have peaches and strawberries in my freezer from our garden so those could supplement in the fruit/veggie category - on top of pancakes, french toast, with a batter for cobbler, or just thawed out in a bowl!
Obviously, I have eggs/toast, pancakes, or french toast, or biscuits/gravy for breakfasts (most of that comes from my staples)
Lunches: sandwiches, carrots
Dinners: we love breakfast for dinner, make french bread from staples - use these with some cut up sausages and cheese/peppers from freezer to make hot sandwiches, pasta with sausage, pasta w/o meat, leftovers from at least one meal...and if I didn't buy the PB/jelly (really, it's in my pantry all the time!), I'd add in a couple of those 8-pks of ramen noodles for filler on other meals.
Again, like everyone else has said...it wouldn't be fun, it wouldn't be super healthy but short term it could be done - wow! Now, I might want to try it next week!
