τεμπελόπιτα = lazy pie. A combination of τεμπέλης (indolent) + πίτα (pie or pita bread).
What it means is any pie that avoids the hassle of making a pastry.
And here is a recipe with the added attraction of tsipouro (τσίπουρο) among the ingredients: https://www.bovary.gr/living/taste/tempelopita-i-paneykoli-pita-me-feta-kai-tsipoyro
