Grate the garlic with a Microplane grater or small side of box grater into the bottom of a large salad bowl. Add the sherry vinegar, mustard, hot sauce and pepper to the bowl, then whisk in about 1/3 cup EVOO in a slow stream.
Add lettuce and onions to the bowl and toss to coat. Season the salad with salt to taste. Top the salad with capers, olives, parsley and nuts.
Pre-heat 2 tablespoons EVOO in a large nonstick skillet over medium heat until EVOO is very hot.
Make four sandwiches of bread, Manchego cheese and a sprinkle of chopped Piquillo or roasted peppers. Press with a brick covered in foil or with a smaller skillet weighted with full cans. Press and grill the sammies in the skillet until deeply golden and cheese has melted, 5-6 minutes, turning once.
Cut sammies in half and serve next to HUGE piles of spicy Spanish salad.
