The Mandu Potstickers are pre-made and frozen. But the veggies, noodles, soup and sauces I make from fresh veggies and packaged products available in any Asian Food Store. (We got a lot of them around here).
The bottled sauces aren’t spicy enough so I doctor them up.
Sounds so good. I recently bought several different bottles of Korean BBQ sauce.
Have yet to try them.
