Nope, it's per weight, that is per 100g for a 550g packet. It's got 3.3g of salt in versus 2 for the lasagne, the Lasagne has 0.5g of salt per 100g, compared to the 0.6g for the Salmon meal.
You're also comparing VERY different types of meal. There is no rule nor much sense in splitting up every meal a day into perfect macro amounts, the reality is some meals have more fat, carbs or protein than others. Lasagne is going to be a higher fat meal, you're talking about pasta in a cheese source, it's absurd to compare it to non cheese source based meal tbh.

A Tesco's finest Lasagne (the only sensible comparison). It has significantly more fat, saturates, sugar and a little more salt. Over 3.5 times the price for a meal with 25% more calories in the same weight.
Here is a look at a finest salmon dish that has a cheese source

Lasagne/cheese source based meals are fat heavy, that is just the way it is. ready meals across the board, cheap £1 ones and expensive "finest" or equivalent ones, are in general crap. They'll use cheap fat sources, cheap bad quality cheese, they'll remove stuff like fat with this "must make it as low fat as possible to appear healthy" BS they've been doing for 20 years and replace it with more sugar and salt to replace the lost flavour.
Too many people simply believe that if the ready meal costs 3 times more it's 3 times higher quality.... not much chance. It's the nurofen vs generic thing. People pay more for non generic for really no reason at all with zero difference between them. A lot of finest products are near enough identical, often with something fancy thrown in to make them appear more upmarket like, croutons in your lasagne, then put it in nicer more expensive looking packaging then charge you more.
Nutrient wise there is precisely nothing that looks healthier about the expensive Iceland or Tesco ready meals. The only 'healthier' thing about the Salmon one is that it is Salmon and not lathered in a cheese source.
I generally never feel worse, as with many others in this thread, than when I eat cheap premade meals out of convenience.
The biggest problem is bad food/diet makes you feel worse, have less energy, sleep worse, feel worse both physically and mentally, more likely to gain weight. When you feel like crap the idea of spending 20 mins or more cooking over 30 seconds taking something out of the fridge and putting it in a microwave is enough to push people into buying more ready meals, then people get stuck in this bad eating cycle.... and you end up with a nation with an epidemic of obesity.

You make time. Well, I make time because for me eating well is part of what is important to me. It's like making time to get to the gym or do exercise. Sure it means I get up earlier to prepare my food, but so what?
