I have a 3750 at a remote site and Nexus at the core and currently both sites are connected through a fiber running eigrp.
I would like to add another layer 2 service connecting between the remote and core site for redundancy.

there is only one instance of eigrp running in our entire network
please advise me with configuration ideas

To achieve rendandancy between two sites through second link using same instance of eigrp , just change delay of this link (second) in manner to influence eigrp metric , by this way your second link become active when the main link is down.

EIGRP you have a awesome feature called offset lists which can suit your requirement.
the higher bw link would be your primary link without altering any metrics, for the secondary link you can worsen the metric with the help of offset lists.
