Making root veggie latkes out of leftover boiled veggies from cornbeef dinner?

Why not turn them into Bubble and Squeak....?
Roughly chop all the ingredients and anything else you may have left over, season add 1 egg mix well. I think peas and asaparagis would go weel with this just add as much as you like!
You can make individual patties in a saute pan, or add a teaspoon of baking soda and bake them in a muffin tin for individual servings. Another idea is to bake whole in a lasagne pan and divide into portions.

I don't see why not. I would drain them really well and add some grated white and sweet potatoes to the mix. Add flour, eggs, a little bit of matzoh meal, and lots of salt and pepper. Fry them up nice and crisp, and you're good to go.
