I made asparagus last night for 3 adults. I did a 1# bunch and there were left-overs but not a lot. We are asparagus lovers and I will put the left-over to good use so I would do 1&1/2# for 6 adults.
I used to steam mine but my son showed me how to stir fry it just before eating. Don't cook it any other way now!!! Toss generously in olive oil and add a few crushed red peppers. Fry over med-hi heat in a big skillet shaking and/or turning frequently. Only takes about 5-8 min. You can ... or not ... use sauce on top of this method.
Happy eats! Pork tenderloin and asparagus go fantastic together!!!
