living in Tucson one of my favorite philanthropies was the local Safeway supermarket would a couple times a year bring over a huge batch of Hatch green chiles and grill 'em up in these big iron barrel-grills out in front of the store. Buy a bag for $5, with $1 going to fight Breast Cancer or whatever the chain's philanthropy of the month was.
Get those, some Texas Ranch beans,
tortillas (partial to flour myself), a rotisserie chicken, "mexican" four cheese shredded cheaese mix and some good sauce (Cholula, Tapatio, Gringo Bandito) or some thicker salsa and you've got two days of fantastico gringo burritos.
(Both Frontera - Rick Bayless - and Mrs Renfro are great, but PROTIP! Swerve the Ghost Pepper Salsa. Jog on, soft lads, not worth it. )
