Sinh tố trái cây are popular Vietnamese snack drinks. The phrase literally translates to "fruit vitamins", but you know them better as smoothies.
This particular smoothie is flavored with jackfruit (mít in Vietnamese). The secret ingredient though is the mung beans (đậu xanh), which provide a creamy and consistent texture. The fresh ripe fruit gives a natural sweetness to the smoothie, which is enhanced by the addition of condensed milk and ice cream.
