How to Make It
Place steak and cornstarch in a bowl; toss to coat. Combine sugar, 3 tablespoons water, and soy sauce in a bowl, stirring with a whisk until smooth.
Heat a large skillet over high. Add 1 teaspoon canola oil and 1 teaspoon sesame oil; swirl to coat. Add steak to pan in a single layer; cook 5 minutes or until done, stirring occasionally. Remove steak from pan; keep warm.
Reduce heat to medium-high. Add remaining 1 teaspoon canola oil and remaining 1 teaspoon sesame oil to pan. Add broccoli, onion, and carrot; cook 5 minutes, stirring frequently. Add snow peas, garlic, and ginger; cook 1 minute. Add steak and soy sauce mixture to pan; bring to a boil, scraping pan to loosen browned bits. Serve immediately.
