Cook the bacon until very crisp. Drain on paper towels until cool; crumble.
In a food processor, puree the beans until very smooth, about 30 seconds. Drizzle in the olive oil and Tabasco; pulse 5-6 times or until combined.
Stir in half the bacon and scallions. Pour into a serving dish and top with remaining bacon and scallions.
Serve at room temperature or chilled.
