Preheat oven to 425 degrees F. Line a baking sheet with foil.

Pour enough boiling water over dried tomatoes to cover. Let stand 10 minutes, drain. Cut into thin strips; set aside.

Place beans and garlic in food processor. Cover and process until smooth.

If using French bread, cut bread in half lengthwise; then cut each half crosswise into 4 pieces. Scoop out the soft center of the bread and discard.

Place the bread, scooped side up, onto the prepared baking sheet.

If using French bread, spread about 1/8 to ¼ cup of marina sauce on each piece; if using pizza crust, spread marinara sauce evenly over entire crust.

Spread about 3 tablespoons of beans over sauce if using French bread or spread all of the beans over the entire pizza crust.

Sprinkle each French bread piece evenly or pizza crust with oregano followed by spinach leaves, tomatoes, and cheese.

Bake until bread is toasted and the cheese is melted and bubbling, about 12 minutes.
