Warming Up Casserole on Shabbat
I’m a little confused about how to warm up food on Shabbat. I understand that you can only put fully cooked solids on the hot plate, but I’m not sure if casseroles count as solids. Generally I avoid the issue by eating cholent, which just stays in the cooker till you’re ready for it, but I’ve invited people over for Shabbat during pesach, and I was thinking of making lasagna. I’m a vegetarian, so making chicken won’t work. How can I warm up a cheese casserole? Thanks!
