Preheat the oven to 350° degrees.
Slice top off the head of garlic and remove papery skins. Drizzle with 1 Tbl. olive oil. Wrap in foil and roast in oven for 30 minutes. Once done, squeeze the roasted garlic cloves out of the head.
Meanwhile, if not using canned, fire roast the red pepper (see instructions in recipe post) and par-boil the tomatoes to remove the skins and seeds. Set aside.
Toast the slivered almonds in the oven for 7-10 minutes or until just beginning to brown. Set aside.
Heat remaining olive oil in a sauté pan over medium-high heat. Once hot, sauté the bread cubes lightly browning all all side.
Add the roast garlic cloves, fire roasted red pepper, tomatoes, toasted almonds, toasted bread, vinegar, salt, smoked paprika, parsley and red pepper flakes to a blender or food processor. Puree until fairly smooth.
To finish the sauce, add to a shallow rimmed baking pan and bake for 15 minutes. This will allow the sauce to thicken slightly and caramelize around the edges.
Yields 1 1/2 cups of sauce. To store, allow to cool and refrigerate in an air tight container for up to 7 days.
