Instructions
1
Cook the orzo in a large pot of salted water until al dente. Drain well. Place orzo in a big mixing bowl and drizzle with a bit of Low FODMAP Lemon Salad Dressing while it is still warm - just enough to coat.
2
Wash, dry, trim and thinly slice the cucumbers crosswise and add to the now room temp orzo. Add the halved tomatoes, dill, parsley, scallion greens and lemon zest. Add enough salad dressing to coat. Taste and season well with salt and pepper. Allow to sit for 15 minutes for flavors to meld and serve. We much prefer this freshly made. If you want to refrigerate, please bring all the way back to room temperature before serving and be prepared to refresh with a bit more dressing. You can try refrigerating in an airtight container for 24 hours.

Tips & Notes
Pro tips
Cook orzo 1 minute under al dente, then shock in ice water to halt cooking—it continues softening as it sits with the dressing.
Use only the green parts of scallions (white and light green are high FODMAP); finely chop to distribute flavor evenly.
Toast or lightly char tomato halves before adding if you want deeper flavor and less watery dressing.
Zest the lemon over the finished salad just before serving to preserve bright citrus notes.
Substitutions
Seedless cucumbers → English cucumber or zucchini (softer texture)
Cherry tomatoes → diced bell pepper (green is low FODMAP; red/yellow are high)
Dill → chives or low FODMAP basil (adjust quantity to taste)
Coarse mustard in dressing → Dijon mustard (use same amount)
Storage & make-ahead
Refrigerate in an airtight container for up to 3 days; dress lightly just before serving to prevent sogginess.
Equipment
Microplane or fine zester (for lemon zest)
Common Questions
Can I make this salad ahead of time?
Yes. Assemble the orzo and vegetables up to 4 hours ahead, then dress just before serving to keep it from getting soggy.
Is this recipe truly low FODMAP?
Yes, when made with low FODMAP orzo, using only the green parts of scallions, and the specified lemon dressing without garlic or onion.
What can I substitute for gluten-free orzo?
Use regular orzo if you don't need gluten-free, or swap for low FODMAP gluten-free pasta in a similar shape.
Can I use fresh basil instead of dill?
Basil is low FODMAP in small amounts. Use the same quantity, though the flavor profile will be more Italian than herbal.
How long does this keep?
Refrigerate in an airtight container for up to 3 days. The orzo will soften and absorb more dressing as it sits.
