You calling it elvanse makes me suspect you have access to maultaschen. Bürger vegan maultaschen (Typ 1) have macronutrients in the proportion suggested by nutritionists; taste good raw, sautéed, or in soup; cost <€2,50; and keep very well. Other varieties are possibly similar, but I don’t know if they can be eaten raw or how they keep.

Plus, they’re a good base for taking elvanse.
