If you are ever trapped in a situation where it's your turn to cook for other people then Spaghetti bolognaise, or any type of roast are pretty easy to do. With the roast you barely have to do anything, just chop stuff up and add a bit of oil & salt then throw it in the oven and set a timer.

If you are cooking for yourself then grilled dinners are easy. You make a salad which is just some type of leafy greens mixed with cherry tomatos, plus whatever else you want to add like cheese or nuts. Spash salad dressing and mix it up. Then grill any type of meat (satay chicken, lamb cutlets, chops, steak or whatever) and put it on the side.

If I am feeling super lazy, I make that exact same salad but add tuna/salmon instead of grilling meat.
