Trim bell peppers, remove seeds, and slice thinly. Trim both ends of bok choy, slice thinly, and place in a large bowl of cold water for a few minutes to remove any grit. Remove by handfuls and immerse again in a fresh bowl of cold water. Drain in a colander.
Preheat oven to 350°F. Place almonds on a baking sheet and roast for 10 minutes, tossing once or twice. Meanwhile, heat 2 teaspoons olive oil in a large saute pan or wok. Add pepper and saute on medium-high heat for 3 minutes. Stir in garlic and continue to saute for 3 more minutes. Remove and set aside in a medium-sized bowl.
Heat remaining 1 teaspoon olive oil in pan. Add washed bok choy and saute for a minute. Add lemon juice and cover pan, letting bok choy wilt. Return peppers to pan, add roasted almonds, and stir gently before serving.
