In a bowl, mix prepared bell peppers, tomatoes and onions with 1.5 tablespoons of the olive oil.
Place on a lined sheet pan and roast at 350F in oven for 30 minutes (you can see coloration of roasting).
On another pan, toast the bread and almonds together for a nice brown coloration (about 10 to 15 minutes).
Cool off, when warm, place the vegetables and all other ingredients in Vitamix blender or immersion blender.
Blend from a rough consistency to very fine depending on your intention to use.
Taste for seasoning, label, and refrigerate.
