Cook bacon in a large skillet over medium-high heat until it begins to render
fat; add onion
and cook until just softened, about 5 minutes, then add corn. Continue cooking, stirring or shaking pan occasionally, until corn begins to brown a bit, about 5 more minutes; remove from heat and let cool for a few minutes. Drain
fat if you wish.
Put lime juice in a large bowl and add bacon-corn mixture; then toss with remaining ingredients. Taste, adjust the seasoning and serve warm or at room temperature.
