In a medium pan over medium-high heat, warm 1 tsp. olive oil, garlic, and onion for 2 minutes, or until aromatic. Add zucchini, corn, lima beans, red bell pepper, tomatoes, and green beans, stirring occasionally until tender and tomatoes are wilted, about 7-8 minutes. Add chives and half the dill (reserving remaining for garnish). Season with a pinch of salt and pepper.
