Without trying to defend the majority of their spending (I spend $45k a year and can't imagine spending 6 figures a year), I know plenty of professional couples, including my partner and me, who rarely cook on weeknights, because we are tired and we like the simplicity of a ready-made meal. If you're both making a professional wage it's hardly extravagant, especially if there is a mechanism (like in my case where I'm self-employed, or in the circumstance of someone who's paid overtime) where you can earn a lot more staying back half an hour than it would cost to buy a few meals.
For me, its just as much a health thing than it is a money vs time thing. I'm slowly crawling my way back to regular obese (was morbidly obese) and hopefully to just "overweight" in the future. Part of that has been largely ceasing going out all the time and avoiding pre-packaged meals.
Might I recommend a crock pot? By far my favorite way to cook, wife makes breakfast while I make dinner pre-kid awakening. Usually takes 15 minutes to throw everything in. Set on low for 8-10 hours (use a timer one if you need it to cook less and go to "warm" till you get home). Come home and voila meat and veggies are all done and the house smells of deliciousness (ive done vegan meals too in crockpot).
Aside from that, use of a broiler is extremely easy to cook a couple pieces of fish or steak or chicken or pork loins. Two minutes to lay non-stick AL foil down and season two pieces of meat, while broiling for 15-20 minutes on low (turn once), toss some rice, water and large portion of vegetables into a rice+steam cooker. Next to no cleanup (toss the AL foil).
One can also whip up a rather nice salad by just throwing 3-5 ingredients and a dressing into a giant bowl and stir away. Total time = 5 minutes, take out some work aggression on that stirring action :)
Desert = fruits, the original convenience food of our cave-man ancestors.
I think this is why our dear leader has pointed out many times how commuting long distances is really terrible. I can see why now because a 45 minute commute = 90 minutes total. MORE than enough time to cook, clean, unwind, all eaten up in a car. I wonder how much of people being tired from work is the fact that it takes 10-11 hours out of your day (rat race commutes plus hour lunches) versus the 8 hours actually worked. Our goal is door-to-door 8.75 hours, 15 minutes commute and 15 minute lunch (usually sandwich or salad or leftover).
