Meat: replace with legumes and other protein-rich foods (green leafy vegetables, quinoa and other grains, seeds and nuts, peanut butter and other nut butters), tofu, tempeh, soybeans, seitan (wheat protein)
Eggs: crushed banana, apple cider vinegar, ground flaxseed or chia seeds…
Milk of animal origin: vegetable milk (oat, rice, soy, almond, hazelnut, walnut, coconut, cashew milk)
Prepare milk of plant origin at home:
Soak 100 g of nuts overnight, then mix them in a blender with 1L of water, a pinch of salt and a little sugar (you can use dates or raisins instead of sugar) and then strain. You can make an oatmeal drink in a similar way, but don’t soak the oatmeal overnight.
