Preheat the oven to 375°F.
Slice the broccoli head width-wise in half, leaving the stem intact. Then slice it lengthwise into small pieces with the stem still attached to each piece. the pieces should be long. Spread these out evenly on a parchment-lined baking sheet.
Crumble the tempeh into quarter-sized pieces. Spread them out evenly on a parchment-lined baking sheet.
Drizzle olive oil, the juice from 1/2 of a lemon, and salt on the broccoli and tempeh. Toss to coat, and roast for 15-20 minutes, until the broccoli has slightly browned and the tempeh is crisp.
While the broccoli is roasting, cut the rough tips off the spring peas. Finely chop the mint and the basil and set aside.
Bring a pot of water to a boil, salt it generously and then boil the peas for 4-5 minutes. Immediately transfer the peas to a large bowl of ice water to blanch them.
Transfer the peas to a bowl, add the mint, basil, red chili flakes, juice from 1/2 of the lemon, zest from 1/2 of the lemon and salt and pepper to taste. Add a generous glug of olive oil and stir.
When the broccoli and tempeh are out of the oven, add the tempeh into the bowl with the peas. Stir to combine.
To serve, add the spring peas to the bottom of the plate. Generously sprinkle the broccoli on top. Finish by grating on fresh parmesan and adding a sprinkle of dukkah. Enjoy!
