Step 1

Cook oil and pumpkin seeds (or use reserved cleaned seeds from Winter Squash Bharta) in a small saucepan over medium-high heat, stirring occasionally, until oil around seeds is sizzling and seeds are golden, about 4 minutes. Strain pumpkin seeds through a fine-mesh sieve into a small bowl; set oil aside. Transfer pumpkin seeds to a plate; immediately season with salt and pepper. Let cool.

Step 2

Working in batches if needed, cook green beans in a large pot of boiling salted water until bright green and crisp-tender, about 2 minutes. Using a slotted spoon, transfer to an ice water bath as you go.

Step 3

Whisk lemon juice and sumac in a large bowl; season with salt and pepper. Gradually stream in reserved oil, whisking constantly until incorporated. Working with 5–7 green beans at a time, line up beans and trim stem ends. Smash with a rolling pin to split open. Cut beans into 1" pieces and transfer to bowl with dressing. Toss to coat and let sit at room temperature at least 1 hour or cover and chill up to 12 hours.

Step 4

When ready to serve, cut pear into ½"-thick wedges, then halve crosswise. Add to green beans along with parsley and half of reserved pumpkin seeds; toss well. Top with remaining pumpkin seeds.
