Start by cooking your gluten-free pasta until it is just al dente, which should take about 10 minutes. You will know it is ready when it is tender but still has a bit of a bite. Do not overcook it, or it might get mushy in the salad later.
Once your pasta is done, rinse it under cool water until it feels lukewarm to the touch. This helps stop the cooking process and keeps the pasta from sticking together. Watch out for draining it too well; you want a little moisture for the dressing to cling to.
Add in the shelled peas, cherry tomatoes, shredded carrot, and red onion once your pasta is cool. You will want to mix this until it is all nicely combined and colorful. Do not skimp on the veggies; they add great texture and flavor.
In a separate bowl, whisk together the lemon poppy seed dressing, olive oil, fresh lemon juice, white vinegar, minced garlic, maple syrup or honey, mustard, and poppy seeds until well mixed. It should smell fragrant and tangy. If it seems too thick, you could add a little water or more lemon juice.
Now, pour that lovely dressing over the pasta and veggies and give everything a good toss. You want every bit to get coated in that zesty goodness. Just be careful not to over-mix, or the veggies might get squished.
Taste your salad and sprinkle in sea salt until it is just right. Let it sit for a few minutes so the flavors can mingle a bit. Do not leave it too long, or the veggies could get soggy. Serve it fresh, and enjoy the bright flavors!
