Bring a large pot of salted water to a boil.
Cook the penne pasta according to package directions until al dente.
Drain the pasta and toss with a small drizzle of olive oil to prevent sticking.
Heat the olive oil in a large deep skillet over medium heat.
Add the garlic, yellow squash, zucchini, asparagus, cherry tomatoes, red onion, sea salt, and several grinds of black pepper.
Sauté for 3–4 minutes, or until the vegetables are tender-crisp.
Add the cooked pasta, peas, grated pecorino cheese, lemon juice, and a pinch of red pepper flakes.
Toss everything together until well combined and evenly coated.
Stir in the basil and tarragon, if using.
Taste and adjust seasoning as needed.
Garnish with additional basil and serve immediately.
This Pasta Primavera Recipe is best enjoyed fresh while the vegetables remain vibrant and crisp.
