1. Gardenburgers (original). Contain cheese/milk in their processing. I dislike the vegan boca burger taste, but I'll need to acquire the taste.
Not a big fan of Boca either, Amy's makes a tasty one, or I can do Boca with a marinade
2. Pamesan/feta cheese. These cheeses I get for their strong flavors, and I haven't found any vegan substitutes that I like.
Can't help you here, I gave up cheese (and dairy) before I gave up meat.
3. Pre-made/processed mocha/cappucino drink. Milk solids. This is bad if not only for its sugar content. I'm substituting with coffee, soy milk, and raw sugar. Working well. This is the easiest to drop.
Looks like you're on track here. I like my coffee black and have grown quite a taste for the upper end coffees, with quite an appreciation for each distinct flavor
4. The occasional candy bar craving in the afternoon. Unfortunately there is a vending machine right down the hall which calls... Yipes! Will be trying to substitute with healthy bars such as Clif Bar Nectars or Larabars which are made from pure fruit sources.
You can also try dark chocolates. Again not much of a help here, I don't care for chocolate or any sweet junk food for that matter.
