If you can get hold of PAN maize flour (this is different from Masa Harina) you can make Arepas in your grill. Cut in half, add cheese and stick back in the grill*. Perfect for breakfast (great with avocado and other salad ingredients)

I understand you can make rice in the sous vide also.

Either of these would go with the endless varieties of protein or vegetable or protein and vegetable dishes and stews that can be done sous vide. If you want a bit of variety get a box/block of Japanese curry roux and stick some of that in as well.

* Once cooked and halved, if you hollow one out a little (or ring round it with mayonnaise) you can add an egg and toast it under the grill. Otherwise drop an egg in a greased mold (ceramic, metal or silicon) and cook the egg under the grill that way.
