On each tortilla, spread 1 tablespoon of the taco topper. Spread 1/3 cup rice mixture over half of each tortilla (if necessary, wet hands with cool water to prevent sticking). Top rice with 1/4 each of spinach and crabmeat mixture. Place avocado and pepper strips down center of each tortilla; sprinkle with lemon juice. Starting at filled side, carefully and tightly roll up tortillas. Wrap each tortilla roll-up in plastic wrap. Refrigerate at least 1 hour or up to 4 hours before serving.
