Have 405 g cooked white rice ready. Remove the 340 g turkey SPAM from its can; wash and dry the empty can to use as a mold. Cut the SPAM into nine approximately equal slices (about 38 g each).

Lightly coat a nonstick pan with neutral oil spray. Sear the SPAM over medium heat until browned on both sides, then remove it from the pan.

Pour the 400 g Egg Beaters egg whites into the pan and season lightly with salt. Cook covered over medium heat until fully set, flipping if needed. Use batches if the pan is too small to make a thin sheet.

Cut the cooked egg into nine portions using the clean empty can as a guide or a knife. Cut three full-size nori sheets into thirds to make nine strips.

For each musubi, place one SPAM slice, one egg portion and 45 g cooked rice in the clean can. Invert onto the center of one nori strip, then lift off the can.

Wrap the nori around each stack and place seam-side down. Repeat to make nine musubi and serve while the nori is still crisp.
