Rinse all the veggies very well. Cut the lettuce and red orach leaves and put them in a bowl. Slice the radishes and chop the parsley and scallions.
The cherry tomatoes can be roasted either in the oven or on the stove. I prefer roasting them in a skillet on the stove, as they cook a lot faster. Simply place them in a skillet, drizzle with a little olive oil, and cover with a transparent lid. They'll be ready in about 5 minutes, once they look soft and juicy.
If you have fresh or frozen peas, use a steamer and steam them for about 15 minutes; otherwise, you can use canned peas.
Make the dressing: mix the olive oil, lemon juice, salt, and pepper.
Mix all the ingredients together, except the cherry tomatoes and the dressing. Add the dressing only right before serving.
Put the roasted cherry tomatoes on top.
Serve!
Notes
Store leftovers in an airtight container in the fridge for up to 2 days, but add the dressing only right before serving so the greens stay crisp. No time to steam peas? Canned peas work just as well.
