Hi! Not the same person but I'm in the same process!
Firstly, take it in steps, don't quit all processed food at once. I actually started with eating more veggies, both in the food and as a side salad.
Then read on the products, not all processed foods are equal, and it depends on what more you have in the meal. On meat products I often look at the meat percentages, it can vary A LOT. A sausage with + 80% meat is a lot better than 30%...
You can also look for E-numbers, concentrates, and other additives. How good or bad these are are still being discussed but I'm leaning towards bad, especially if it's a lot.
For example a highly processed sausage with basmati rice and a decent amount of salad isn't the same as said sausage with just mac and cheese.

Some meals are easier to prep than others but more often than not I've found meals, especially the meat, to need time. Time to cook properly!
-
Fry meat in a pan, let it simmer in water for half an hour or so ( I rarely keep time ), make a sauce in the pan.
-
Or put a chunk of meat on a oven safe plate and trow it into the oven on 150-175°C for 1.5-3h or more depending on size and tenderness.
-
Or make a soup, just make sure it boils long enough for the meat! :)
