Bro, that shit ain't nothing but processed crap shit in a box.........
You're kidding right? I mean, eating right before bed is a delicate issue anyhow, but asking if Hamburger Helper would be okay is like asking if french fries are great post-workout.
It's probably the WORST COMBO of FAT/SODIUM/CARBS you can have........even if you use 4% ground beef, you still have tons of sodium/processed white flour product/shitty carb choice.
Expect to store the majority of this shit as fat!
