I am from Monaco, so French way of eating and I don't know/see a single adult who snacks, it is a different culture.
Careful with even healthy snack, because you are maintaining / encouraging the habit and now you are eating veg and cottage cheese, but one day you will crack, and it will be back to a packet of some sort.
Why not try to free yourself from snacking. Go the French way. We only eat seated at the table, not in lounges, bedrooms, cars, walking, bus, ... A week should suffice to break the habit.
Sauces in jars or sachet, dry or not, are pure rubbish, a combination of cheap fats, sugar of some sorts, and a ton of chemicals.
Here are a couple more tips. Vinaigrette : take an empty jam jar, add a generous tablespoon of dijon mustard, then salt ( a must otherwise it won't emulsify) , and 2 or 3 fingers of extra virgin olive oil , a vinegar you like, close lid and shake (above sink safer) . When doing salads, start with tomatoes first, chop or slice them, put in the bowl, and sprinkle coarse salt and add olive oil. The tomatoes will sweat and make juice. Then prepare and chop the other veggies on top, including some fresh onion.
For a chicken breast, you can again chop a tomatoes, onion and why not black olives , sauté them in a pan wit a bit of oil, salt, clove of garlic, then push everything to a side of pan, add chicken breast sliced, brown it and when almost cooked, mix with he veggies. IF the veggies are stuck to pan, a bit of water will make a lovely juice.
Lemon juice, fresh parsley, fresh rosemary, good quality extra virgin olive oil, and - of course - dijon mustard . Put the tiniest amount of oil, sauté your chicken, when cooked, add a spoon of mustard, squeeze a lemon and if you have it a dash of white wine, high flame, mix done enjoy,. Salt and cracked pepper in all recipes of course,
Treat yourself in the true sense of the verb treat as in heal, instead of treat as a noun which attributes some emotional justification for crap.
Treat yourself to a good quality steak, grass-fed, a small piece, the size of your palm, so aim at quality and not quantity.
Embrace colours and discover new flavours combination. Pick one veggies you have never tried before or a new way of cooking one your knew, so raw cauliflower, shaved with a vinaigrette in which you have crushed some garlic, an artichoke , and so on.
What I am trying to say is to not make this change about restrictions or punishment but freedom and new additions to your diet.
A book I really recommend is " On the side" www.amazon.co.uk/gp/product/B06XYR6VPX/ref=dbs_a_def_rwt_bibl_vppi_i1?tag=mumsnetforu03-21 to discover new way of cooking vegetables. Of course, you will have to make some adjustment to reduce butter/oil, but sometimes, just use the real recipe and have half a portion. The celeriac cooked in salt and the okra chips were a revelation.
But careful, when aiming to lose weight, you know you have to eat less quantity, but by having great taste, you won't feel deprived.
