I decided to add the category almost vegetarian and almost vegan to my labels, because some of the dish I cook are vegetarian or vegan if it was not for 1 ingredient. When that 1 ingredient can be, easily and with no major impact on taste, substituted with something else or taken out, I will label the recipe as almost vegetarian or almost vegan.
Here a list of possible substitutions
If the incriminated ingredient is: substitute with:
bacon/pancetta butter or oil if there are no other cooking fats
meat broth vegetable broth
