Season chicken, if desired. Heat 1 Tbsp. (15 mL) Becel Olive Plus™ Oil Blend in large nonstick skillet over medium-high heat and cook chicken, turning once, until thoroughly cooked, about 10 minutes. Remove to serving platter and keep warm.
Heat remaining 2 Tbsp. (30 mL) Oil Blend in skillet and cook tomatoes and garlic, stirring occasionally, until softened, about 3 minutes. Remove from heat and stir in vinegar.
Arrange tomato mixture over chicken, then top with basil and lemon.
