Their verdict: the meals are edible and some have great flavors and textures, but the “steam” technology doesn’t add anything special to the cooking in real terms. Meals didn’t always heat or cook perfectly, which the plastic bag steaming technology was supposed to fix. Cooking times aren’t significantly shorter than most other packaged meals. Neither are macronutrients like calories, fat, protein, and sodium content is pretty much the same.
The steamer baskets and bags might feature meals that appeal to you, but from the solo diner’s point of view, there’s no vast technological improvement. Get the cooking time down to a minute or so and cut back on the sodium–then you’d have some impressive advancements.
