I'm about to do the laziest crowd-pleaser dinner at my house:
Cook up a bunch of white rice with salt and a good amount of dehydrated onion in the water, then dicing up chicken and grilling it. Everyone gets to customize that base. I mix in a bunch of chili crisp and have an easy "Asian" spicy chicken and rice dish. My eldest heats up a can of black beans and adds that to his bowl along with shredded cheese and calls it a "Chipotle bowl." Takes about 30 minutes and everyone gets exactly their style of meal.
