Lasagna calories
There's no single “correct” number for lasagna: every family cooks it a little differently. Built from USDA ingredients, a standard version gives 160 kcal per 100 g, about 480 kcal for a 300 g serving.
A serving covers about 24% of the 2,000 kcal reference day used on US nutrition labels.
A real serving: 403 to 557 kcal

How long to burn one serving
About 15,000 steps, or 116 minutes of brisk walking for an average adult.
How we count: an adult of 75 kg and 175 cm walking at 5.6 km/h burns (4.3 − 1) × 75 = 247.5 kcal an hour above resting. Steps are distance divided by a stride of 0.415 × height. That's about 31 steps per kcal. The Kalorea app uses your own height and weight.
Shoot it from above so the whole plate is in frame. If it's oilier than usual, add “lots of oil” to the description, and Kalorea will lean to the top of the range.
