Which of the 10 Gives the Most Protein per Dollar?
The black bean burger: 12 g of protein for $0.54, or about 22 g per dollar, calculated from the source's numbers. Spicy tuna salad and the 15 bean soup follow at about 20 g per dollar.
Figures come from each recipe page. The last column divides listed protein by listed cost.
| # | Lunch (serving) | Time | Cost | Calories | Protein | Fiber | Protein per $1 |
|---|---|---|---|---|---|---|---|
| 1 | Chickpea Salad (1 cup) | Not listed | $0.57 | 90 kcal | 3 g | 4 g | 5.3 g |

Myth: Bean Lunches Are Low in Protein. Fact: 6 of the 10 List 12 g or More.
Spicy tuna salad (13 g), the wrap (15 g), three bean salad (13 g), 15 bean soup (17 g), the burgers (12 g) and black beans with eggs (23 g) all clear 12 g.
Not all do. The chickpea salad lists only 3 g, and the cowboy caviar 7 g. Treat those as sides or add tuna, egg or cheese.
Myth: Healthy Lunches Cost More. Fact: Dietitians Point to Canned Beans and Tuna.
Sherri Hoyt, RDN, LD, a dietitian at Missouri Baptist Medical Center, calls canned beans her main budget protein in a March 2022 BJC article. She says they can replace beef or pork in many recipes and add fiber.
She also calls canned tuna a cheaper and healthier sandwich filling than deli meat, and says frozen single-ingredient vegetables are nutritionally comparable to fresh. The article is from 2022, so prices have moved since.
Myth: Canned Beans Are Too Salty for a Diet. Fact: Rinsing Cuts About 40% of the Sodium.
Hoyt says rinsing and draining canned beans for about one minute reduces sodium by roughly 40%. Most canned-bean recipes above say to rinse. The exception is black beans with eggs, which uses the bean liquid and lists 160 mg of sodium per serving.
Watch the broth instead. The Mediterranean lentil soup lists 1,452 mg of sodium per serving, and the source says to check that salt is not the first ingredient in the bouillon.
Hidden Sugar and Salt in Budget Lunches: 6 Items to Check
Most of these lunches list no added sugar, but a few ingredients carry it or a lot of sodium.
- Sugar in dressings: three bean salad uses 2 tbsp for the batch, and cowboy caviar ½ tsp.
- Salsa (spicy tuna salad): packaged, so compare sugar and sodium.
- Ranch dressing and refried beans (wraps): packaged, labels vary.
- Sriracha, soy sauce, mayonnaise and breadcrumbs (burgers): all packaged.
- Bouillon (lentil soup): the sodium comes mostly from here.
- Tortillas and buns: not costed or counted in the burger figures. Compare labels.
What Cooks Say About These Recipes
On the three bean salad page, a reader named Tim wrote in April 2026 that he made it lower in calories by using allulose instead of sugar, less oil, extra vinegar and chickpeas for the cannellini beans, and that fresh onion is essential.
On the 15 bean soup page, Trish said she makes it in an Instant Pot: 20 minutes on high pressure with a 10-minute natural release. On the burger page, Janet found her mixture too wet and turned it into a wrap filling instead.
How Long Do They Keep?
Per the sources: chickpea salad 1 day; spicy tuna salad 4 days; cowboy caviar 3 to 4 days; three bean salad 4 days; lentil salad 3 to 4 days; lentil soup 4 days; 15 bean soup 3 to 4 days; cooked burgers 3 to 4 days.
Freezer: lentil soup, 15 bean soup and raw burger patties, up to 3 months. Do not freeze cowboy caviar or the lentil salad.
Action step: This weekend, make one batch recipe, the 15 bean soup or the lentil soup, portion it into 4 containers for the week, and freeze the rest for up to 3 months.
