Onions - white or yellow - I do 2 whole onions for our family (5 eating - 2 adults and 3 small children)
Salt & Spice (or your favorite seasoning)
Slice ends from onions and peal yucky outer stuff. Cut onions in half. Place in microwaveable dish. I use a glass loaf pan because it is as deep as the onions are tall and I know I am less likely to make a mess. Drizzle with olive oil then sprinkle with a pretty heavy hand of seasoning. Cover with plastic wrap or a paper plate or something that will trap in the steam pretty good. Microwave on high for 10 minutes, then check for tenderness. Continue to cook in 5-minute increments until a sharp knife will pierce with little to no pressure. Careful not to overcook though. If overcooked, the onions get soggy and slimy which is unpleasant at best. This one is a HIT will my family. My 5-year-old eats at least half an onion by herself!
