Things I would recommend:
2. Stay on top of your B12 game. If you're in it for health & not animal-related reasons, then just eat an egg once in awhile.
Really I think most of your advice is more like your preferences than advice, and suggesting an egg once in a while for B12 is questionable at best:
http://www.eggnutritioncenter.org/egg-nutrition-facts-panels/
An egg only has
15% of RDA for B12. Is once in a while, 7 times/day?
A single cup of commercial nut milk (like Soy Milk) has 50% B12 RDA. Two cups of commercial nutmilk Or supplement B12 are better options, to cover B12 RDA than eggs.
IMO, Start simple with the essential simple whole plant foods, and then you can worry about things like Vegetable Spiralizers and Bliss balls later if you feel the need.
IMO AIM for two servings of Greens and Legumes (Beans, Lentils, Chickpeas, etc) per day add any other vegetable of your choice, and plant starch of choice(Potatoes are unfairly maligned and great nutrition), through in some nuts/whole grains and
eat enough. The main Vegan mistake is not eating enough because vegetables are nutrition dense, but they are NOT calorie dense.
Do that I bet you hit RDAs and Protein that you require without worrying about tracking anything.
But if you are concerned, just plunk what you are eating into
cronometer occasionally.
If you are eating enough whole plant foods, and including Legumes and Nuts/Seeds, then you really only have to be concerned about:
B12: As previously mentioned Supplement or drink commercial nutmilks. (I do both)
Vitamin D: Nearly Everyone is deficient in Northern latitudes. I have always supplemented 1000 IU/day in winter, and that didn't change with Vegan transition.
If I was going to
recommend One Animal product, once in a while, it would be Fish, Salmon in particular is almost perfect to counter Vegan gaps:
A single Can of Sockeye Salmon has:
400% RDA of B12
250% RDA of Vitamin D
IOW Salmon is overflowing with the two nutrients that are missing from a Vegan diet.
Also it is one of the best sources for Long chain Omega 3 fatty acids, also not found in plants. Though we can synthesize them from Short Chain ALA found in Flax seeds/Walnuts. I have a scoop of flax in my oatmeal every day for a steady supply of ALA.
