Preheat your oven to 425°F (220°C). Line a large sheet pan with parchment paper, a silicone liner or lightly grease it.
Add the gnocchi, chickpeas, diced beet, and sliced zucchini to the pan. Drizzle with olive oil and sprinkle with seasonings. Toss everything and spread it out into a single layer on the sheet pan.
Roast for 25 to 30 minutes, stirring once halfway through, until the gnocchi are golden and slightly crispy and the veggies are soft and caramelized.
While the gnocchi and veggies are baking in the oven, make the cashew garlic sauce. Add all of the ingredients to a blender and mix.
Once everything is roasted, remove the pan from the oven. Spoon the pesto over the gnocchi and vegetables while still warm so it melts in a little. Drizzle the cashew sauce and balsamic glaze over top, then finish with crumbled feta.
