Begin by washing your green bell peppers and jalapeño. Cut the bell peppers into small pieces and dice the jalapeño according to your heat preference. If you prefer a milder Matbucha, remove the seeds from the jalapeño before dicing.
In a large skillet, heat the extra virgin olive oil over medium heat. Once hot, add the chopped green bell peppers and diced jalapeño. Sauté for about 5-7 minutes, or until the peppers are soft and slightly caramelized.
Stir in the minced garlic, paprika, chili pepper flakes, and salt. Continue cooking for another 2-3 minutes until fragrant. The garlic should become golden but not burnt.
Add the diced tomatoes to the skillet. If using fresh tomatoes, ensure they are peeled and diced as finely as possible. Stir the mixture well to combine all the flavors.
Sprinkle the sugar over the tomato mixture and stir to combine. Allow the Matbucha to simmer on low heat for about 20-30 minutes, stirring occasionally. This will help the flavors meld together and the sauce to thicken.
After simmering, taste your Matbucha and adjust the seasonings as needed. You might want to add more sugar for sweetness or more chili flakes for heat, depending on your preference.
Once finished, let the Matbucha cool slightly before serving. It can be enjoyed warm or at room temperature. For the best flavor, allow it to chill in the refrigerator for a few hours or overnight before serving.
