Fresh or dry herbs and spices, flaked/dried seaweed - used in place of salt and flavor enhancers. They all work very well. Also, making my own seasoning mixes in place of chemically enhanced blends/packets has helped to replace them with a healthier sub.
Dried onions and garlic - diced, flaked, powdered - used in place of fresh if not available. These have really come in handy during times of immediate need.
All natural dehydrated potato flakes - used in place of recipes that call for misc. flour needs or used as a thickener.
Heart healthy oil in place of butter and all natural applesauce in place of oil or egg in some recipes.
Raw local honey or agave nectar in place of sugar... Dried dates in place of sugar... fresh and dried fruits in place of sugar/sweeteners.
Coconut water in place of sugary un-natural electrolyte and energy drinks
Beans, legumes, peas in place of meat
Grated raw nuts in place of grated cheese - this is perfect for raw vegan dishes
Coconut or nut milk in place of dairy milk - all the best when I can make it fresh too... I use to make a lot of fresh coconut milk from beautiful fresh coconuts
Fresh sliced citrus, ginger, mint, cucumber, etc. thrown into ice water to flavor in place of some really unhealthy drinks out there, chemically flavored waters/beverages and those mix in flavor packets...
