Cook brown rice in pot or rice cooker according to package directions. While rice is cooking, heat sesame oil in a saut pan, skillet, or wok. Add sliced bell pepper and edamame, and saut for 6 minutes. Add bok choy and soy sauce and cook, for an additional 4 minutes, just until bok choy is crisp-tender yet still bright green. Divide rice among 4 large bowls and top each bowl with one-fourth of the vegetable mixture.
