Roughly cut the bell peppers into large segments and place them in a roasting tray with the vine tomatoes and the garlic cloves. Drizzle with 2 tablespoons olive oil and season with salt. Place the tray into the preheated oven to roast for 25 minutes, until the skin on the peppers and tomatoes is blistered.
Heat a frying pan to medium-high heat. Dry toast the almonds for 3-4 minutes until they begin to color and smell roasted.
Remove the roasting tray from the oven and allow the vegetables to cool for 5-10 minutes. When they're cool enough to handle, peel the skins off the bell peppers and peel and deseed the tomatoes.
Place the veggies in a food processor with the roasted garlic cloves, toasted almonds, smoked paprika, and sherry vinegar.
Pulse the food processor to blend the ingredients together, until a thick, textured sauce forms.
Serve as an accompaniment to fish, chicken, or vegetables, in a sandwich, or mixed with pasta.
