(The onion is a red herring.)
Oh, except really, you start with some couscous. Put a cup or so of dried couscous in a heatproof bowl, and stir in a little olive oil, salt, and chopped scallion. Boil a kettle of water and pour it over everything. Stick a plate on top of the bowl and then go about your business with the rest of the meal.
Now back to the veggies. Grate the sweet potato coarsely. Heat some peanut oil in a big skillet and stir fry with some ginger, garlic, and salt until it starts to get tender. You don’t want to overcook it, because it will get all mushy and then the texture won’t contrast with the couscous.
Stick a lid on the skillet to steam the asparagus, but again, watch the timing. Overcooked asparagus can be tragic.
This is a really fast dinner. Grating is a good technique to remember for root vegetables when you don’t have an hour to spare before you risk collapsing from hunger on the kitchen floor.
Sweet Potato and Asparagus Couscous
serves 3-4
1 cup couscous
1 Tbsp olive oil
2-3 scallions, finely chopped
1 large sweet potato
1 lb. asparagus, trimmed & cut into bite-sized pieces
1 inch fresh ginger, peeled & grated
2 cloves garlic, minced
1-2 Tbsp peanut oil
salt
Toppings: harissa; sriracha; Tabasco; etc.
Boil a kettle of water. Mix up the couscous with the olive oil, chopped scallions, and 1/2 tsp salt in a heatproof bowl. Pour about 1 1/2 cups of boiling water into the bowl, stir it up, and put a plate on top of it.
Heat the peanut oil over medium-high heat in a large skillet. Grate the sweet potato and add it to the pan with the ginger, garlic, and a little salt. Stir fry for a few minutes, until the potato is starting to soften. Add the asparagus pieces, stir, and put a lid on the pan until everything is just tender.
Scoop some of the couscous into a bowl, and put some of the cooked vegetables on top of it. Dress it with the sauce of your choice.
