Heat 1/2 tbsp of olive oil in a taller saucepan. Add couscous and stir for 2 minutes to toast it a little. Add 1 1/2 cups of water or stock and butter, salt if using water and taste liquid if salt is needed. Cover saucepan and simmer for 8-10 minutes. Stir occasionally.
Remove from heat once all liquid is reduced. Add in half a lemon, if you want more citrus flavor, add full lemon. Add in chopped herbs that you like most. I used cilantro. A combo of mint, parsley and cilantro would be great too.
