I swear by Pru Leith's Vegetarian Bible. She lists the recipes by vegetable family, and within that the veg themselves, so you can go straight to ideas for the things you want to use up, or have found a glut of in a market.
With that lot, I think I'd do chicken and mushroom pies, parsnip soup and twice-baked jacket potatoes, freezing some of each, as there will be more than you'd need for two. What's in the bag above the chicken pieces?
The three bags on the right have half a small roast chicken (cooked), bacon bits (from a local farmer according to the label) and mushrooms.
I'll look out for Pru Leith's book. I'm not veggie, although I'm happy to go out without meat and don't eat much.
The constraint I have is that I'm diabetic and have a low carb diet. Apart from avoiding sweet things, I very rarely eat potatoes, bread, pasta, rice or pastry, but my partner does.
I think I'm turning into my grandmother. As children, we used to squirm when she went into shops at the end of the day and more or less begged for anything which was going spare.
