As a single male in his mid 20's this thread screams my name. I do very little cooking and my meal prep takes me about 20 mintues for the week. Here's an example of my daily menu.
Breakfast - oikos triple zero yogurt
1st snack - 1oz roasted peanuts
Lunch - 3oz shredded chicken with 1 oz of shredded cheese (I buy a rotisserie chicken and shred it for the week)
2nd snack - 2 hard boiled eggs (usually can only eat the whites)
Dinner - 3oz meatballs with 1oz cheese
3rd snack - 1 individual sized smart pop popcorn bag
I do want to start adding more greens and fiber into this routine but it has worked out well so far.
