Other posters are mentioning pre-cut, frozen veggies as a shortcut. Which is fine for a lot of dishes, where the veggies come out soft. (In many areas where produce has to travel a long ways from where it’s grown to where it’s sold, frozen veggies often have more nutrients, because they’re preserved shortly after harvesting.) Frozen veggies also let off more water into whatever you’re cooking, so you might consider defrosting and draining them first, if needed.
Rice takes 30-40 minutes to cook, unless you’re just microwaving that ready-made rice in plastic bowls (hello microplastics), and stir fries are better with rice that’s a day old. It’s also better if you slice up your meat thin and velvet (marinate it with egg whites, cornstarch, and/or a tiny bit of baking soda) it for at least half an hour, and if you put eggs in yours, those are best scrambled in their own pan and added to the dish shortly before it’s finished, otherwise the eggs will cling to everything else while cooking and be essentially “lost.” That’s definitely not “minutes” worth of cooking.
If you make like a shitty American version of a taco (with just ground beef, pre-made taco seasoning from a packet, hard taco shells, lettuce, cheese, salsa from a jar, maybe a dollop of sour cream), that might take 15-20 minutes or so, but if you’re making real, Mexican style tacos (soft tortillas, meat like carnitas or birria, fresh salsa and other sauces, fresh veggies, etc.) that takes much longer.
If you plop raw veggies in your frittata, that’s a quick meal, but it might not turn out as well as if you had sautéed the veggies with the seasonings first (heat brings out the flavor of the seasonings, especially if cooked with a fat, and improves the texture of some of the veggies that would take longer than the eggs to cook.)
Again, not saying that cooking dinner takes the same amount of time and effort as every other household chore combined (unless maybe if you live in a very small home?) but that cooking and cleaning up afterwards is a bigger task than you’re making it out to be, if you’re taking care to make things tasty.
