I have baked it with marinara sauce and frozen peas and carrots.
Also made it in the microwave in a covered pyrex dish covered halfway with water and spice the same as usual with carrots, celery, and onion, some salt and pepper and sugar). It microwaved for 40 minutes and was great.
Also like to defrost (2 each)salmon gefilte fish loaves and white fish loaves, mix each one with an egg, ground onion and carrot, and some sugar and salt, and add red chrein to the salmon. Then I either layer the fish in a loaf pan (white gefilte fish, salmon g.f., white, salmon) and bake it covered for about 45-50 minutes or until the top is very firm, or I take a spoon and throw dollops of alternating fish into the pan and then marbleize it with a knife and bake it the same way. It makes for a really spectacular presentation when sliced, and I hollow out (nearly to the bottom) a section of unpeeled cucumber (cut off the ends first) and fill each section with chrein and put it on the side of the slice of fish. Looks SO pretty.
