Zatarain's Spanish Rice 6.9 oz (195g) package (per serving: .5g fat, 4g protein, less than 1g sugar, 400 mg sodium 4.5 servings/pkg) Add water, butter, and a can of diced tomatoes. Mix of rice (no pasta) with spices. Definitely the heartiest of the three but maybe was edged out by the chewy texture of the rice. Price November 2017 in SLC, UT: $1.49
Disclaimer-I bought all three packages at regular price and we tried all three on the same night just out of curiosity. We've also made homemade Spanish Rice with just rice, water, and salsa. Homemade is still definitely better but for everyday we like the Rice-a-Roni best as both a side and a topping for homemade burritos, tacos, and the like. We liked the Zatarain's best when paired with a salad for nights when we're copying restuarant salads like Costa Vida or Cafe Rio. I was not compensated in any way from any company or individual.
