In a food processor, combine imitation crab, eggs, and peppers and pulse to chop and combine. Transfer mixture to a medium bowl and add mayonnaise, panko, chives, lemon juice, garlic powder and salt. Stir to combine and form into 4 (½-cup) patties.
Place on a greased sheet pan, cover with plastic wrap and refrigerate at least 1 hour or overnight.
Heat olive oil in a sauté pan over medium high heat. Cook patties for 8 to 10 minutes per side or until golden brown and heated through. Place each “burger” on an English muffin with 1 lettuce leaf, 1 tablespoon Easy Tartar Sauce, and a few cucumber slices.
