Asparagus heralds the arrival of spring, especially when slathered in this vibrant, make-ahead romesco sauce of tomatoes, bell peppers and almonds, spiked with chilies and spices. No mystery why Catalonians put it on everything from meat to fish to veggies! Bonus: This recipe makes a large amount, so after the guests have gone, pull out the leftovers and take some baguette for a dip. Consider it the home advantage.
