Start by heating a wok or deep skillet over medium-high heat until it shimmers, then add the neutral oil. Swirl to coat the pan evenly.
Add the finely minced garlic to the hot oil and stir quickly. Cook for about 15 seconds, until fragrant and slightly golden, filling the kitchen with a pungent aroma.
Immediately add the sliced carrots, spreading them out in the pan. Stir constantly for 3-4 minutes until they start to caramelize at the edges and turn a bright, tender-crisp texture.
Add the thawed peas straight from the freezer and stir quickly. Cook for another 2 minutes, until the peas are heated through and vibrant green, giving a slight pop when pressed with the spatula.
Pour in 1 to 2 tablespoons of soy sauce, stirring constantly to coat all the vegetables evenly. The sauce should shimmer, infusing the dish with savory depth.
Finish by drizzling 1 teaspoon of sesame oil over the stir fry, tossing gently to distribute the aroma and toasted flavor throughout the vegetables.
Remove from heat and let sit for a minute, allowing flavors to meld and the dish to settle. Transfer to a plate and garnish with sesame seeds or chopped scallions if desired.
Serve immediately while hot, enjoying the crisp texture and bright flavors that evoke a sunny garden afternoon.
