I ran into the same problem this week. Before you throw it out or feed it to the birds, here are some tips.
Croutons for salad. Toss with a little oil, salt and any other seasonings you'd like (I like a dash of garlic powder). Toast in a frying pan, or on a cookie sheet in the oven (but SET A TIMER if you do). They will last over a week when sealed properly and your dinner guests will be impressed.
Make panzanella. This is one of my favorite things. It's an Italian bread salad with lots of added "stuff." Add anything you like. I like olives, capers, roasted tomatoes and tossed in olive oil and balsamic vinegar. It's a creative alternative to pasta salad and works well for picnic season.
