Your personal best way to lose some fat - anecdotes / experiences / examples of what kicked your ***

I want to do more meal prepping, but am having trouble settling on recipes, and having a hard time getting more interesting ways of including enough vegetables.
You have any good references or recipes for prepping? I am a good cook, but with 4 kids I also have trouble sustaining it. Like two weeks of prepping in a row and then I just want to spend all that time doing other stuff.
