Frequently Asked Questions
What’s the best way to grill vegetables?
Cut in uniform sizes, toss generously with olive oil, salt, pepper. Use medium-high heat and turn frequently for even charring. Grill baskets work great for small pieces.
Can these recipes be made ahead?
Yes! Most hold well for 2-3 days refrigerated. Salads taste better after flavors meld. Roasted/grilled veggies reheat beautifully or serve at room temperature.
Are these recipes vegan?
Most are naturally vegan. Omit cheese/butter where noted. Nutritional yeast makes great Parmesan substitute.
How do I pick the freshest summer produce?
Look for firm texture, bright color, heavy-for-size produce. Farmers markets offer peak ripeness. Store tomatoes and ethylene-sensitive produce separately.
