Heat the olive oil in a large pan over medium heat. Add the onion and bell pepper and sauté until softened, about 5 minutes.

Add the paprika, salt and pepper. Stir to combine. Add the red wine vinegar and let cook for 1-2 minutes. Add the tomatoes, garlic, and sugar and stir to combine.

Simmer on medium-low, stirring occasionally, until the ingredients reduce down to a thick, tangy, sweet sauce, about 45-60 minutes.

Taste and adjust for seasoning. Let cool and serve alongside your favorite summer spread.
