Pretty much all (or at least most) Indo snacks can be frozen. Which is pretty fortunate for me, because currently

I have a household of two. Can you imagine trying to work your way through eating fourty lumpia (spring rolls)?!

they go straight from my freezer into the oven. Will tell you exactly what and how in the recipes.
