Sooooo, as promised, I've forensically analysed a Jack recipe, in this case Simple Tomato and Bean Soup.
I've used the package data from the packaged stuff, and the SELF website date for the fresh food.
1 carrot (using 1 US cup as an average carrot) – 52 calories
2 garlic cloves 8 calories
I medium onion 44 calories
Stock made with a cube 30 calories
Asda baked beans per tin 330 calories –
minus 70 for the sauce being rinsed 260 calories
Asda chopped tomatoes 1 tin 310 calories
Total calories 704
Recipe is for four people so 176 calories per person.
If this is an entire meal it is not nutritionally adequate for a growing child - you would have to add a couple of slices of bread and butter to bring it up to around 400 calories. No mention of the tiny calorie count in the recipe itself.
Jack describes it as "a hearty, filling soup suitable for lunch or a light supper" - at 176 calories it is neither hearty nor filling. And the costing of 20p per portion is misleading, since a quarter of that recipe would not fill a shrew.
