Preheat oven to 400°F, and line a baking sheet with parchment paper. Add sliced peppers, jalapeño, garlic, and whole tomatoes to the baking sheet. Drizzle all with a bit of olive oil, sea salt, and pepper. Roast for 20 -25 minutes or until the veggies char a bit. Let cool, then place all ingredients in a blender with some water, (adding just enough so that it can blend smoothly), cumin, and a big splash of olive oil.
