How to Make It
Heat oven to 400 degrees. Spritz centers of 4 foil sheets with cooking spray. Combine rice with water; spoon equal amounts onto each foil sheet. (Make a temporary lip around the edges to contain water, if necessary.)
Layer 1/4 beef over rice; top with 1/4 peppers.
Seal packets; place on foil-lined baking pan. Bake for about 30 minutes, or until beef is heated through and rice is tender.
