Place the pork loin between two sheets of parchment paper and pound with a meat mallet until 1/4-inch thick.
Season both sides of the pork cutlet with sea salt, black pepper, and garlic powder.
In a shallow bowl, whisk the egg until smooth; place the almond flour on a separate flat plate.
Dip the pork cutlet into the egg wash, then press into the almond flour until evenly coated on both sides.
Heat 1 teaspoon of olive oil in a large non-stick skillet over medium-high heat.
Add the pork to the skillet and cook for 3 to 4 minutes per side until the coating is golden brown and the pork is cooked through.
In a small jar or bowl, whisk together the remaining 1 teaspoon of olive oil, lemon juice, and Dijon mustard to create the dressing.
In a large bowl, toss the mixed greens, sliced cucumber, and halved cherry tomatoes with the lemon dressing.
Slice the crispy pork schnitzel into strips and serve immediately over the dressed salad.
