I went to a tapas party last night and brought grilled and roasted veggies with romesco sauce. Everyone thought the sauce was amazing and requested the recipe so I thought post it just in case anyone is looking for a good appetizer to make. I recommend using Muir Glen's roasted tomatoes to save time and adding an extra unseeded pepper for more heat. I felt it didn't need the bread or wine the recipe called for.
BTW all the suggestions regarding my previous post about avoiding soggy veggies worked out great. I used firmer veggies and the more watery ones I either roast or grilled at a high heat so they were toasty on the outside but warm and crunchy on the inside. I placed everything on parchment paper after grilling and roasting. I think it made a huge difference.
