Bring a large pot of salted water to a boil and cook orzo pasta until tender, about 7 to 8 minutes. Before draining, reserve 1/2 cup of the pasta water and set aside. Drain pasta in colander and set aside.
Meanwhile - season the shrimp with the salt, pepper and red pepper flakes. Heat a large skillet over medium - high heat and add in the avocado oil. Once hot, sear the shrimp on both sides, until they begin to turn pink and curl up. This should take about 3 minutes.
Toss in the butter, garlic, reserved pasta water and snow peas. Squeeze the juice of the lemon into the pan and cook until the butter is melted into the sauce.
Remove the pan from the heat and stir in the cooked orzo pasta and fresh tomatoes. If desired, zest a little lemon peel over the top to boost the lemon flavor and season with more crush black pepper. Enjoy!
