These little guys are so handy for a quick meal. If you are wanting to grab a quick breakfast or lunch and you don't have access to a full kitchen, this microwave cooker might just be for you. With eggs, you simply line the pot with cooking oil or spray, crack an egg inside(breaking the yolk). Add any cheese, veggies or seasoning you like and microwave for a minute. To steam veggies, you just place raw vegetables in the steamer, add 1/4 cup water with your seasonings and microwave 3-5 minutes. These are also dishwasher and oven safe. There are slight variations in the sizes, average dimensions are 3" tall and 4" wide.
