In a food processor pulse, chop the spinach, adding a few handfuls at a time, and with the last handful, add the mint leaves, chili pepper and juice of lemon.
In a medium saucepot over medium-low heat, warm the stock or broth.
Heat a risotto pan or rounded bottom pot over medium-high heat, add EVOO, onion and garlic, soften 2-3 minutes, add rice and season with salt and pepper, and toast the rice 2 minutes. Add wine and let it absorb while stirring rice with wooden spoon or risotto spoon (a spoon with a hole at its center to build more starch as you stir). Add a few ladles of stock at a time and stir vigorously to build a creamy, starchy risotto. From the first addition of the stock, the risotto will take 18 minutes to prepare to al dente. In the last 3 to 5 minutes, add the spinach mixture and peas, then just before serving, melt in the butter. Finish with cheese, and adjust salt and pepper.
