If using homemade pesto, make it now; if using store-bought, have ½ cup ready. Cook 1 cup rice according to package instructions and set aside.
Preheat the oven to 400°F (200°C).
On a large baking sheet (or two baking sheets to avoid overcrowding), spread the chopped sweet potato, cauliflower florets, zucchini, carrots, red onion, yellow squash, and red bell pepper in a single layer.
Drizzle 2 to 3 tablespoons avocado oil over the vegetables, sprinkle 1 teaspoon garlic powder and ½ teaspoon sea salt, then use your hands or a spatula to toss until all pieces are evenly coated.
Roast the vegetables on the center oven rack for 18 to 20 minutes, or until they are golden brown with a bit of char, stirring or shaking the pan once halfway through if needed for even browning.
While the vegetables roast, prepare an ice bath: fill a bowl with ice and cold water. Bring a pot of water to a full rolling boil.
Using a slotted spoon, gently lower 4 to 6 eggs into the boiling water. For jammy yolks cook 6 minutes; for firmer yolks cook up to 10 minutes. When the time is up, immediately transfer the eggs to the ice bath and chill at least 15 minutes.
Peel the chilled eggs and, if desired, halve them.
To assemble two bowls: divide the cooked rice between the bowls, top with the roasted vegetables, add the peeled (or halved) eggs, sprinkle ¼ cup raw pumpkin seeds over both bowls, and drizzle each with the ½ cup pesto (divide the pesto as desired). Serve immediately.
