Errr How does steak and potatoes take a couple hours? Begin washing potatoes. Let your pan heat up for about 5 minutes on high. Boil potatoes in the microwave for 10 minutes, finish by pan-frying for another 5... While potatoes are in microwave, start cooking the steaks, they'll be done before the potatoes are out of the microwave.... Boiled spinach sounds nasty, I much prefer steamed, but that takes about 2 minutes, which you can use while you're frying the potatoes. Normally you'd have multiple things running at once, the entire meal shouldn't take more than 30 minutes from the time you enter the kitchen... Hell, I can run to the grocery store, purchase all the ingredients, come home and still be done in under an hour.
I'm a little confused, what caused the difficulty? One thing I notice from your pictures is that it looks like you went to great lengths to separate your seasonings into separate containers... don't worry about that, just put it all on a cutting board and let the flavors mix together, the reason they do that in cooking shows is to make each ingredient stand out, and also so they don't have to show each herb being diced up into small pieces.
Same with your other food... a metal spatula can serve double purpose for flipping your steaks as well as serving the potatoes, you could have pan-fried the potatoes instead of putting them into the oven, in the same pan you cooked your steaks on while your steak is finishing after removing it from the heat... No reason you can't season your steak in the package it comes in.
1 plate, 1 pan, 1 microwave safe bowl. 1 spatula. Chef Knife. Cutting board. Fork.
Cleanup becomes much easier and quicker as well.
It doesn't have to be complicated.
And for erronious... while broiling, the oven door should stay open the entire time, that's why they have the hinge that lets it stay partially cracked. It's a direct heat source doing the cooking, not the air temperature, of the oven.
