Well, they are healthy for a variety of different reasons:
Substituting tahini for butter. Tahini is packed full of nutrients that butter simply can't compete with. Besides offering less fat and calories, tahini provides more protein, anti-oxidants, anti-inflammatory, compounds, and powerhouse vitamins like manganese, phosphorus, thiamine, and vitamin B6. BOOM. (Check out this article for more information about tahini's reason to brag.)
Replacing whole eggs (white and yolk) with *whipped* aquafaba. Though you give up nutrients inherent to eggs, using aquafaba for these pancakes reduces the overall calories and fat in the recipe. This is a great option for those who suffer from dairy allergies, or are following a vegan diet.
Truvia Sweet Complete reduces sugar. Pancake batter is not exactly knowing for being a sugar bomb (that comes with the additives and toppings, usually), but I'm all for reducing granulated sugar where possible. Truvia Sweet Complete works with an additional teaspoon of pure vanilla extract to ultimately smooth the flavors of tahini and aquafaba, while creating a little more sweetness.
