There's nothing quite like the feeling of driving down interstate 5 from Sacramento and seeing all the produce grown. It can be humbling to drive among the various orchards and realize just how much produce is produced on the valley floor.
Grains: For an extra boost, add a cup or so of cooked grains. Farro, quinoa, or sorghum. This salad is versatile enough that most grains work.
Bread: I'm a sucker for a salad with croutons and this one would be perfect with homemade croutons. Just a heads-up though, add a bit more dressing so that it can soak into the bread.
Cheese: Swap out the halloumi for another solid salad cheese like crumbled gorgonzola or feta. If you're using feta, try your hand at grilling it!
