Preheat the oven to 350 degrees. Slice the baguette into thin pieces and layer them across a cookie sheet lined with aluminum foil. Brush the tops with olive oil, then bake for 25 minutes, or until they begin to brown.
Drain the can of tomatoes very well, then combine in a bowl with the feta, basil, garlic powder, salt and pepper and mix gently.
Spoon (or scoop) onto toasted baguette slices and enjoy!
