In a food processor, blend the cream cheese until smooth. It needs to be at room temperature or the consistency may become lumpy when mixed with the other ingredients.
Add the feta, Greek yogurt, garlic, oregano, and lemon juice.
Once combined, transfer to a baking dish and bake, covered, for 25 minutes.
Transfer to a serving dish and top with diced tomatoes and freshly ground pepper.
Serve with crackers, pita chips, pretzels, French bread, or veggies!
