Preheat the oven to 300°F (150°C).
Line a baking sheet with parchment paper. Lay 20 small slices of bread out in one layer.
Lightly brush one side of the baguette slices with ¼ cup olive oil; you might not use it all. Place in the oven for about 20 minutes or until they are slightly golden. It might take more or less. Make sure they're not too soft when you remove them. You must bake them in a low oven to dry them out so they're crunchier and don't get soggy quickly.
Remove and immediately rub with 2-3 garlic cloves, peeled and cut in half. They will disintegrate quickly, infusing the flavor into the bread. Allow to cool before assembling.
Beat 8 ounces cream cheese, softened, 1 ¼ cup feta cheese, crumbled, 1 teaspoon dried herbs, and a little salt and pepper in a medium bowl until it is mostly smooth; it will still be lumpy from the feta. Taste and adjust seasonings.
When cooled, spread the cream cheese mixture onto the slices. Top with ½ cup sun-dried tomatoes, cut into strips, dividing evenly. Sprinkle ⅓ cup chopped green onion on top.
Drizzle with extra olive oil. Serve immediately.
