Cut the grapefruit in half and place it on a baking tray or in an oven-proof pan; cut side up.
Sprinkle the grapefruit halves evenly with a dash of salt and a drizzle of maple syrup.
Place the grapefruit under the broiler for about 3 minutes or until the edges are bubbly and slightly browned. Keep a close eye on it to avoid over-broiling.
While the grapefruit is broiling, toast the nuts in a dry pan over low heat for about 3 minutes or until fragrant.
Serve the broiled grapefruit halves with the toasted nuts on top. Enjoy!
Notes
Nuts: Try almonds for the most fiber, almonds, peanuts, or pistachios for the most protein, and walnuts for the most quality fats.
