All the time! Whenever I buy junk food for groceries, I generally eat it the first day. There are NO fast food places within a 10 mile drive from my home that are open untill after like 10pm except a rather expensive and not that great pizza place.
A few decent solutions I found:
-Buy a very large bag of grated cheese and deep freeze it. You can keep it in the freezer for 1, maybe even 2 months! Cook pasta, then add oil / butter / cheese / cream / fried bacon and stir well untill it makes a creamy sauce. Add bacon if you happen to have it.
-Ramen noodles with leftovers (fried vegetables / meat) and soy sauce and/or ketchup
-All kinds of sandwiches. Add extra butter / cheese / mayonaise etc.
-5 minute microwave chocolate cake mugs (use google for recipes, there's plenty!)
