Estimate calories in this FDOE

I have been trying to calculate the calories of my meal plan in hospital to try estimate how much I should be eating at home, any help is appreciated!

Breakfast- was two bowls of porridge with 200ml Semiskimmed milk and 20g honey alongside a coffee

Snack – 2 wheaten slices, 20g cheese, 7g butter and 20g jam

Lunch – jacket potato, 7g butter, chicken fillet in gravy and veg

Snack – 2 pancakes, a banana, 7g butter, a oat iced latte with sugary syrup

Dinner – beef lasagne, jacket potato and peas

Snack – 4 weetabix, sugar, 200ml milk and a banana

I estimated ~2800-3000 calories but I could be wayyy off
