Looking at a random Pot Noodle it in itself is not terrible but obviously could be better, and probably not great to have every day and it will depend what else you're eating and doing in the day.
Obviously the one you're eating may be slightly different but there's 10g of saturated fats in that and men are recommended 30g per day. Also quite a bit of salt but honestly try finding pre-packaged food that ain't.
If you want food that is satiating try and go for some complex carbs (wholegrain breads, rice, pasta, noodles etc) and unsaturated fats (avocado, olive oils, peanuts, brazil nuts, almonds - although with nuts bear in mind a few is all you need). Complex carbs burn slower so keep you full longer, but don't have the instant hit (and crash) of uncomplex carbs like sugars. Fats are more satiating and unsaturated fats are better for you for that reason.
If you can meal prep why not try knocking up some chicken burritos, freezing them and either defrosting the night before or lightly grilling every day? Or salads (yes yes, you don't win friends) with some cold meat and topped with some chopped almonds and olive oil. Or pep buddha bowls as they offer great versatility. If you google there's many examples but a Mexican-style one could be black beans, sweetcorn, quinoa, bell peppers, cherry tomatoes, meat of choice and some avocado. You can prep all that (save the avocado) in advance.
Appreciate you mentioned it has to be cheap but often if you meal prep it can work out cheaper in the long run as a Pot Noodle is what, 80p-£1.20 depending on size/brand?
