Here's one of my carefully developed hacker easy dinners, refined over a number of years, optimized for minimal prep and cleanup time, cost, and healthiness:

  * Family-size package of bone-in chicken thighs with skin
  * 4 cups white rice
  * Bag of frozen vegetables
  
  1. Preheat oven to 400°.
  2. Salt and pepper chicken.
  3. Place chicken on half sheet pan.
  4. Bake for approximately 20 minutes, until the juices run completely clear, with
     no trace of pink, when a fork is inserted.
  
  While the chicken's cooking:
  
  1. Place rice in saucepan.
  2. Add 2 cups water (or as much as the package instructions say).
  3. Bring to boil.
  4. Turn heat down as low as it goes, stir, and cover pot.
  5. Cook for approximately 15 minutes, or until all the water has been absorbed. Do
     not lift the lid until the end, to check whether the water's been absorbed.
  
  5 minutes before the chicken and rice are done:
  
  1. Place frozen vegetables in a microwave-safe container.
  2. Add a few tablespoons of water.
  3. Microwave for 5 minutes.
  4. Salt and pepper.

Upsides: It takes 20 minutes, it will all be ready at the same time, there are only two pieces of cookware to clean, it makes enough for dinner for a week, and it costs about $10 total.

Downsides: It doesn't taste very phenomenal. But, hey — cooking food that tastes good is what makes cooking time-consuming.

The chicken will taste better if you brown both sides in some butter and vegetable oil in a frying pan first, but that takes more time. If you don't want the carbs in the rice, you can switch in some black beans.
