Couscous halloumi salad. Super fast to prepare, and easy to modify with any veggies on hand (onion, red pepper, broccoli), or substitute feta for halloumi. Short on time, no need to grill the cheese, just cube it and toss into the warm couscous to get a little melty while you prep the veg. Tasty on it's own - I've never even tried it with the dressing.
I make this every year for cheap-but-wonderful Christmas presents for family and friends. And I always make sure that there is enough made so that I can keep at least six jars for myself. This is brilliant on cheese sandwiches, in a chili, or to pep up some chicken wings.
