The basics of cooking really is that simple. Making a meal is no more than a few minutes. Of course you can get as creative as you want, which can add time but it's overall a simple task. If you have a skillet, salt and pepper and fire you're done!
Take your preferred piece of meat. Steak, pork/lamb chops, whatever. Put your skillet on the fire and let it heat up. While it's heating up you salt and pepper the meat (add whatever ingredients you like but the basics are salt and pepper). Rub in the salt and pepper. By now you're skillet is well heated. Put your meat on the skillet and set fire to medium. 3-5 min on each side depending on the thickness of the meat and your preference for rare, medium or well done. And that's it. Max 10 min and you have your meat. If you want a side dish...say a potato. While you're meat is cooking wash and place the potato in the microwave for 2 - 4 min depending on size! Potato cooks at the same time as the meat. You're not wasting your whole day.
I made these in a little over an hour
Or say you're home all day and want to make something for dinner. Take 2 racks of ribs, you're preferred liquid to cook in. Can be Pepsi, beer, broth, just about anything. Season the ribs just like mentioned above. Can be however basic or complicated you want. Put the ribs on a slow cooker, pour the liquid all around till it covers the ribs. Set the slow cooker on low and wait 5 hours. You literally don't do anything to it. After 5hrs a quick 2 min on the skillet and done. The slow cooker doesn't even require you to be home although I dislike leaving it on in an empty house. You can also leave it overnight and it cooks while you sleep.
You can go as crazy or as basic as you want and still have something that tastes great
