Step 1: Cut all vegetables into smaller pieces if necessary to fit into your blender or food processor. Wash all vegetables thoroughly and peel the garlic.
Step 2: Add all your vegetables into a blender or food processor. Add oregano, Maggi cube, olive oil, salt, and black pepper. Blend until smooth.
Step 3: Spoon the blended sofrito mixture into ice cube trays with lids, filling each compartment nearly to the top. Secure the lid on the tray.
Step 4: Place the tray in the freezer and freeze for at least 4 hours, or until the sofrito cubes are completely solid.
When cooking, pop one or two cubes into a pan as a base for rice, beans, stews, or meats.
