Place roasts and 1 cup water in a 6-quart pressure cooker.
Cover cooker with lid, and seal securely; place pressure control over vent and tube. Cook over high heat 8 to 10 minutes or until pressure control rocks quickly back and forth. Reduce heat to medium-low, and cook 40 minutes. (Pressure control will rock occasionally.)
Remove from heat; run cold water over cooker to reduce pressure. Carefully remove lid so that steam escapes away from you.
Drain meat, reserving juice. Pour juice into a fat strainer; let stand until fat rises to top. Reserve juice; discard fat. Cool meat slightly, and shred.
Sauté onion and green chiles in hot oil in the cooker for 1 minute. Stir in green salsa and next 4 ingredients. Cook 1 minute over medium-low heat. Stir in reserved meat juice and shredded meat. Cook 5 minutes or until thickened. Serve on kaiser rolls with green salsa, if desired.
