I've come to realise myself, cooking something very edible is not hard. Buy a physical cook book so as to not get distracted on the internet, and just try some things. The first couple tries at a new recipe might turn out slightly weird, so what? You'll still get the satisfaction of having produced something yourself, it won't kill you, and it'll be a whole lot healthier than ordering or microwaving fast food. Plus you'll know exactly what's in it because you put it there.
Should you ever not have time to stand around in the kitchen, a loaf of bread, some jam and ham should do it. Add in some bacon, spread, whatever, and you've got dinner ready to go in the time it takes to take all of that out of the fridge. Heck, slice a couple pickles! There's so many ways to eat well and tasty if you just try for a moment.
Though of course, not getting fucked over by your ingredients requires you to look at them before buying. Hoo-hah.
Preferably tomatoes grown in volcanic soil, like San Marzanos.
It is well worth buying one can of several different brands of tomato sold in your locale, and making experimental taste-test batches with all other variables held constant. With good quality inputs, you can beat the pre-made jarred marinaras every single time, using nothing more than a very basic recipe and a minimum of cooking skill.
Exercise caution. Once you know how to make a good sauce, you will never be able to stand eating at Olive Garden again.
