- Preheat the oven to 400 degrees F. 
- Drizzle the bread on both sides with olive oil. Place the slices on one half of a sheet pan. 
- On the half side of the sheet pan, toss the asparagus with olive, oil, salt and pepper. Arrange the spears in a single layer. 
- Roast the bread and asparagus until the asparagus turns bright green and the bread is toasted and golden brown. Flip the bread about halfway through cooking. 
- Rub the bread on both sides with the garlic clove and then mince it. Halve the asparagus spears. 
- In a large saucepan of salted boiling water, cook the peas for 2-3 minutes until they are just tender. Using a slotted spoon, transfer the peas to a bowl of ice water to stop them from cooking. Drain the peas once they have cooled. 
- In a small bowl, mash the peas with the minced garlic, lemon juice, salt and pepper. 
- Spoon the smashed peas on the toasted bread. Arrange the asparagus on top. 
- Sprinkle with parsley, chives, flaky sea salt and pepper before serving.
