I'd try doing what we do with green tomatoes that have to be picked. Try it with some of them anyway. Wrap them individually in newspaper and lay them in a cardboard box in a single layer. Put the box in a cool dark place and check them every few days. Many will ripen up more.

It works well with tomatoes without having to resort to the fake ethylene gas type ripening you get with the paper bag with several pieces of ripe fruit added.

Otherwise I'd use them to make a chutney with so all the other additives would give it more flavor.

Pears should be picked prior to full ripeness. If left to ripen on the tree, they are too ripe. After picking them put them in a cool, dark place or in the refrigerator for chilling for a few days. I place them in single or double layers (with newspaper between layers) in cardboard boxes, but don't need to cover them or wrap them individually. Depending on how green they are, they may need to ripen for 1-3 weeks. If the flavor still isn't great, don't give up on these pears. The fruit on many types of fruit trees doesn't reach full flavor potential when the tree is young. Give it another year or two to decide on the flavor of the pears. If these were really just too green, you might try making pear mincemeat with them. We have such a squirrel problem, that I often have to pick the tree a little bit greener than I'd like, so I know first hand that they do ripen nicely after picking. The variety of your pear also makes a big difference in flavor. One of our pears is a cooking pear, and doesn't taste very good eaten fresh, but makes good pear cake and pear pie. The other one produces pears that make wonderfully sweet juice without having to add any sugar at all. Good Luck. I never knew I liked pears so much until I started canning them.

We buy those green ones from the store, hard as bullets. My DW then puts them in her undies drawer, given a few days they go yellow and super ripe. Peeled and eaten just as they are.
We do have a Bartlett pear next door, and occasionally the neighbor passes some over the fence and we use the same treatment. I believe the term is 'Coddling'

Another view on pears - those picked from a tree, not store purchased...
