To prepare salad, pat tofu cubes dry with a paper towel. Heat 1 teaspoon oil in a large nonstick skillet over medium-high heat. Add tofu; sauté 5 minutes, browning on all sides. Remove from pan; chill 30 minutes.
Cook pasta in boiling water for 5 minutes; add beans, and cook an additional 5 minutes. Drain. Rinse with cold water, and drain. Combine tofu, pasta mixture, tomatoes, and dill in a large bowl.
To prepare dressing, combine vinegar and remaining ingredients in a jar; cover tightly, and shake vigorously. Pour dressing over salad; toss well to coat. Cover and refrigerate 30 minutes.
