No, but something to absorb liquid from the vegetables is needed. Meats don't ooze liquids like vegetables do, and in order for these fresh vegetable lumpia to hold up as well, something starchy is needed. You could substitute 1 cup of grated, white potato. Add and cook with the other vegetables. Or, 1 cup of cooked rice, add to cooked vegetable mixture instead of the mei fun or rice noodles.
