Peel and quarter onions. In a large bowl stir together oil and honey. Add onions, garlic, and salt, stirring well to coat. Transfer mixture to a lightly greased 2-quart baking dish.
Bake in a 350 degree F oven for 30 to 40 minutes or until onions turn golden brown, stirring occasionally. Remove from oven; let cool.
Transfer mixture to a food processor bowl or blender container. Cover and process or blend until smooth. Serve on toast points or crusty French bread rounds. Refrigerate any remaining spread, tightly covered, for up to one week.
